Still Liquid Line × Wicking × Base
A liquid line that barely moves is often a normal loss your eye cannot see. Weigh the bottle, calibrate it with water, and blot a reed tip — then you will know whether it is stuck, slow by design, or fine.

CSI materials for the base-vs-reeds test — 25 black fibre reeds and 300 g of Pure Performance, in your own bottles with your own base and oil · CSI live pricing, October 2026
Quick answers — read this first
Is my diffuser actually stuck? Weigh it first. In the example bottle a normal 1.0 g/day lowers the line only 5.6 mm in two weeks. Calibrate your own bottle with 10 g of water.

Wicking or base? Blot a reed tip on white paper. Wet tip = liquid climbs but leaves slowly (release). Dry tip, dark only part-way = liquid stalls (wicking).

What is the quickest test? Wicking glasses: three fresh reeds in an open glass of each liquid, climb marked at 15 min, 1 h, 4 h and 24 h.

What does the bottle test cost? ₹1,211.00 in CSI materials in your own bottles with your own base and oil (₹4,008.00 with everything bought). See the kit.
The short answer
Answer: First confirm the bottle is really slow by weighing it — a normal loss can be invisible by eye. Then blot a reed tip: wet tips with low weight loss mean slow release; dry tips mean poor wicking. Only then test base against reeds.
Why: Bottle shape hides small losses. Slow release comes from the carrier, reed count and exposed length; poor wicking from the reeds, reed ends on the glass, or a blend that is not fully compatible.
Method: Weigh on days 0, 3, 7, 14; calibrate the line with water. Run 24-hour wicking glasses in two bases, blend and plain. Then three arms of three bottles: current base and reeds, a second base, fresh reeds.

"Barely changes": calibrate the bottle, then follow the reed Left: example calibration of your own bottle (10 g of water raises the line 4 mm). Right: two questions, in order. day 0 line −4 mm per 10 g (your calibration) In 14 days, at an example rate of… 0.4 g/day → 5.6 g lost → line drops 2.2 mm 1.0 g/day → 14.0 g lost → line drops 5.6 mm 2.0 g/day → 28.0 g lost → line drops 11.2 mm 1 · Weigh it. Is g/day really low? Bottle + reeds on a scale, days 0, 3, 7, 14. Your eye cannot see 1–2 mm. 2 · Are the reed tips wet? Blot a reed tip on white paper; look for darkening to the top. Tips WET, g/day low Release-limited: liquid climbs Tips DRY, g/day low Wicking-limited: liquid stalls but does not leave below the tip Test: second base, more reeds (the slow-release question) Test: wicking glasses, fresh reeds, plain base vs blend A level that "barely changes" is often a normal loss your eye cannot see. Weigh before you diagnose.
Left: calibrating your own bottle — in the example, 10 g of water moves the line 4 mm, so even a normal release rate lowers it only a few millimetres in two weeks. Right: once weighing confirms a slow bottle, a blotted reed tip separates release-limited from wicking-limited, and each has its own test.

Straight answer
My reed diffuser liquid level barely changes after two weeks — does that suggest poor wicking or an unsuitable base?
Neither, until you have weighed it. A still liquid line is often a normal loss your eye cannot see; grams per day is the evidence. Weigh the bottle with its reeds on days 0, 3, 7 and 14, and calibrate the line by adding 10 g of water to a spare identical bottle: in the example, that raises the line 4 mm, so a normal 1.0 g a day lowers it only 5.6 mm in two weeks. If the bottle really is slow, blot a reed tip on white paper. A wet tip means the liquid climbs but leaves the reed slowly — a release question about the base, reed count and exposed length. A dry tip on a reed dark only part-way up means the liquid stalls — a wicking question about the reeds, reed ends sitting on the glass, or a blend that is not fully compatible. Then test: 24-hour wicking glasses in two bases, and three arms of three bottles — your current set-up, a second base, and fresh reeds. That costs ₹1,211.00 in CSI materials in your own bottles with your own base and oil.
One line: weigh it and calibrate the bottle before you call it stuck — then a blotted reed tip tells you wicking from release.
Before you buy anything, weigh the bottle and calibrate its liquid line with water — both are free. If the weighings confirm a genuinely slow bottle, the test needs a 25-pack of black fibre reeds (₹236.00) and three 100 g packs of Pure Performance Base (₹975.00) to separate the reeds from the base, in your own 100 ml bottles.
See Pure Performance 100 g

First, is the level really not moving?

Your eye is a poor instrument for a reed diffuser. A gram a day can look like nothing for a fortnight.

A reed diffuser loses liquid slowly by design, and the change in the liquid line depends on the shape of your bottle as much as on the diffuser. In a bottle with a wide body, a whole week's loss can lower the line by a millimetre or two — invisible unless you marked it. So before deciding between "poor wicking" and "unsuitable base", find out whether there is anything to explain. Two measurements settle it, and neither costs anything if you own a kitchen scale.

The first is weight: weigh the bottle with its reeds in on the same scale at the same time of day, today and again in three and seven days. Grams lost divided by days is the release rate, g/day, and it is the only number that cannot be fooled by bottle shape or lighting. The second is a calibration of your bottle's line, done with water in a spare identical bottle: add 10 g of water and measure, with a ruler against the glass, how far the line rises. In the worked example that is 4 mm per 10 g — an example; your bottle will differ. Now you can translate g/day into the millimetres you were expecting to see. At an example 1.0 g/day, two weeks removes 14 g and lowers that example line by only 5.6 mm. At 0.4 g/day it is 2.2 mm.

EXAMPLE calibration (4 mm per 10 g) and EXAMPLE g/day values — replace both with your own
What "barely changes" means in grams, millimetres and days
If your bottle loses In 14 days Line drop in the example bottle Days to empty an 85 g fill Is it "barely changing"?
0.4 g/day 5.6 g 2.2 mm 212 days Yes — and it may be too slow
1.0 g/day 14.0 g 5.6 mm 85 days Looks still by eye, but releasing normally
2.0 g/day 28.0 g 11.2 mm 42 days Should be visible with a mark

If your weighings put you in the middle row, nothing is wrong with the wicking or the base: you have a diffuser releasing at a steady rate in a bottle that hides it. Whether the room smells strong enough is a separate question — the section hub and the bedroom post cover that. If you are in the top row — a very small loss, with a weak room — read on. That is a genuinely slow diffuser, and the rest of this page separates the two causes you named.

The CSI principle
Weigh before you diagnose. A still liquid line is an observation; grams per day is evidence.
Calibrate your bottle with water once, and you will never again mistake a normal fortnight's loss for a blocked diffuser.

Poor wicking or slow release: the one look that separates them

Once the scale confirms a slow bottle, there are two quite different reasons, and one observation tells them apart: how far up the reeds the liquid has reached. Pull one reed, blot its top end on white paper for a few seconds and look at its colour along its length. If the tip is wet and dark, the liquid is climbing all the way; it is just not leaving the reed surface fast enough. That is a release problem — a slow-evaporating carrier, too few reeds, too little reed exposed above the neck — and the saturated-reeds post owns the full test. If the reed is dark only part of the way up and the tip is dry, the liquid is stalling below the top. That is a wicking problem, and it is the one this page tests in depth.

Release-limited versus wicking-limited · what you see, what usually causes it
Which slow diffuser do you have?
Release-limited Wicking-limited
Reed tips after 3 days Wet, dark to the top, blot leaves a ring Dry; dark only part-way up
After a flip Short burst, then quiet Strong burst (you have put wet reed in the air), then quiet again
Commonly described causes Slow-release carrier by design; few reeds; short exposed length Reeds that wick poorly in this liquid; blend not fully compatible (haze can clog); old or coated reeds; reeds pressed hard on the bottle floor
Cheapest test More reeds in the same base Fresh reeds in the same base; wicking glasses
Base change worth testing? Yes, after the reed test — 7963 Only if the plain base wicks well and the blend does not — see below
Check the reed ends before anything else
Look at the bottom ends of your reeds. Reeds pushed hard against the bottle floor, cut at an angle that seals against the glass, or with ends crushed during packing can draw liquid poorly. Lift them a few millimetres so they stand in liquid rather than on glass, and re-check the tips in two days. It costs nothing.

Wicking glasses: a 24-hour test you can watch

Put reeds in an open glass of each liquid and watch them climb. The reed that stalls in the glass will stall in the bottle.

This is a quick screen, not a verdict, and it isolates wicking from everything else — bottle neck, room, fill level. You need small clear glasses (your own, or a Silicon Measuring Beaker 100 ml at ₹300.00 if you want a graduated one), 30 g of each liquid, and three fresh reeds per glass. Mark each reed with a fine pen at the liquid surface, then mark how high the darkened band has climbed at 15 minutes, 1 hour, 4 hours and 24 hours. The worked example compares your blend in Softness Base with the same oil in Pure Performance Base, both at 15% Jasmine; add a glass of each plain, unscented base if you have spare base, because that tells you whether the fragrance oil is changing how the base wicks.

Wicking-glass screen · 30 g of liquid per glass · 3 fresh reeds per glass · mark climb height in mm (labelled working practice)
What to record
Glass Liquid 15 min 1 h 4 h 24 h Tip wet at 24 h?
G1 Softness + Jasmine 15% (your blend) ___ ___ ___ ___ Y / N
G2 Pure Performance + Jasmine 15% ___ ___ ___ ___ Y / N
G3 (optional) Softness, plain ___ ___ ___ ___ Y / N
G4 (optional) Pure Performance, plain ___ ___ ___ ___ Y / N

Read it like this. If reeds in your blend (G1) climb to the tip in a day, wicking is not your problem in principle, and the bottle itself — reeds standing on the floor, a neck that pinches them, too little liquid left — deserves a look. If G1 stalls and G2 climbs, the base is a real suspect for wicking with this oil. If G1 stalls and G3 (plain Softness) climbs freely, the oil is changing how the blend behaves — check clarity, because a slightly hazy blend can deposit at the reed surface. The cloudy-after-mixing post covers compatibility in depth. CSI publishes no viscosity for any base, so this glass test is the practical substitute.

Round one: three arms in your own bottles

The glasses tell you where to look; the bottles tell you what to buy. Use three of your own 100 ml bottles per arm, each with an example 85 g fill — 12.75 g of Jasmine and 72.25 g of base at 15% — and 6 reeds. Arm C uses fresh black fibre reeds so that reed source is the only change. If you have run out of spare bottles, CSI's 120 ml Gold bottles work, but then use them for every arm, never mixed with your own.

The common mistake: replacing reeds and base at once. A maker with a slow bottle buys a new base and new reeds, the new bottle moves, and they reorder both for production. If the reeds were the whole problem, every future bottle carries a base change it never needed — with its own clarity and life retesting. Fix: arm B changes only the base, arm C changes only the reeds. Combine them only if both help.

What a slow bottle costs, and what each fix costs

A slow diffuser is not cheap just because it lasts. At CSI rates the 85 g of liquid in Softness costs ₹213.63 (12.75 g of Jasmine at ₹4.30/g and 72.25 g of base at ₹2.20/g at an example 1.00 g/ml; ₹221.99 to ₹206.07 across ±5% density). If it releases at the example 0.4 g/day it lasts about 212 days at ₹1.01 of liquid per day — but if the room scores 1, that is ₹1.01 a day for almost nothing. The same liquid in Pure Performance costs ₹289.64 if you buy the base as 100 g packs and ₹213.63 as 500 ml at the example density (the 500 ml is cheaper per gram for any density above 0.676 g/ml).

Argued against our own interest, plainly. Two of the most likely answers on this page — "the loss was normal, you just could not see it" and "lift the reeds off the bottle floor" — sell nothing. The next most likely is a ₹236.00 pack of reeds. A base change, the one that earns us most, is the last line, and only after a glass test and a bottle test both point at it.
A bottle that barely moves is either releasing quietly or stuck. A scale, a ruler and a reed blotted on white paper tell you which.

Three 100 g packs of Pure Performance (₹975.00) cost less than a 500 ml bottle (₹1,099.00) for arm B's 249.5 g; buy the 500 ml only if arm B wins and you move to production. Jasmine's 15 g (₹103.00, ₹6.87/g) carries the usual small-size premium over its 100 g (₹4.30/g).

Why trust this guide

CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished diffusers. A base seller could answer this title with "change your base". This page puts weighing and a free water calibration first, then a reed-end check, then a 25-reed pack, and only then a base — and it states that CSI publishes no viscosity or evaporation figure for any base, so the glass test is the practical substitute.

Base, reed, bottle and tool prices are CSI live pricing, pulled 14 October 2026. Fragrance-oil prices are CSI live pricing, pulled 24 September 2026, stock re-checked 14 October 2026. Every gram of oil and base, every millilitre-to-gram conversion, per-bottle liquid cost and kit total on this page is computed and shown to two decimals so you can check it. Densities used for conversions are labelled examples — none is published for any CSI base or oil.

Bottle counts per arm, rest periods beyond the base pages' 24–48 hours, weighing days, room-scoring scales and evaluator panels are labelled working practices, not industry standards — none exists for reed diffuser throw.

Frequently asked questions

Why is my reed diffuser not going down?
Often it is, just too slowly to see: a gram or two a day can lower the line by only a few millimetres in two weeks. Weigh the bottle with its reeds on fixed days. If grams per day really is very low, check whether the reed tips are wet.
How do I know if my reeds are wicking?
Pull one reed and blot its top on white paper. A wet ring and a reed dark to the tip mean it is wicking. A dry tip on a reed dark only part-way up means the liquid is stalling. You can also watch fresh reeds climb in an open glass over 24 hours.
Can a reed diffuser base be too thick for reeds?
A carrier that wicks poorly in a given reed would show as a stalled climb in a wicking glass. CSI publishes no viscosity for its bases, so compare your base with a second base, plain and with your oil, in glasses and then in bottles.
Do reed diffuser reeds stop working?
Reeds can wick less well over time, especially if residue builds up at the surface. Test fresh reeds in the same liquid beside your current reeds. If the fresh set is clearly faster and stronger, replace them.
How much should a reed diffuser evaporate per day?
There is no standard figure. It depends on base, oil, load, reeds, bottle and room. Decide the product life you want, weigh your bottles, and compare grams per day with that target.
Should reed diffuser reeds touch the bottom of the bottle?
Reeds pressed hard against the glass floor can draw liquid poorly. If the neck allows, let them stand a few millimetres above the floor in the liquid, the same way in every bottle, and check the tips after two days.
Weigh before you diagnose
Calibrate the bottle. Blot a reed. Then test base against reeds.

About this guide: Written by the CANDLEMAKINGSUPPLIESINDIA team. The weighing, bottle calibration, reed-tip check, wicking glasses and decision rule apply to any reed diffuser from any supplier; the products named are CSI's.

Customer reviews: The six reviews at the top of this page are genuine, published Judge.me reviews left by CSI customers on the product pages named on each card — Eco Candle Wicks, Premium Candle Wicking Needle and Bamboo Wick Holder. They are general product reviews, not assessments of the guidance set out here. Names, star ratings, dates and products are as recorded by Judge.me and wording is unedited. "Verified buyer" appears only on the three reviews Judge.me recorded as verified — Monika Deep, Subhankar Roy and Sneha Tamang; the reviews from Ashwini, LJ and Lalitha Jagan are published but not recorded as verified, and carry no badge.

Non-price figures and assumptions: Load convention: fragrance load is a share of the total blend by weight (oil g = batch g × L; base g = batch g × (1 − L)), as the base pages put it, "of total blend". Worked example: the reader's own 100 ml bottle with an example 85 g fill at an example 15% = 12.75 g oil + 72.25 g base; 30 g of liquid per wicking glass. Example density 1.00 g/ml (±5% at 0.95 and 1.05); Pure Performance breakeven density 0.676 g/ml. Example calibration 4 mm per 10 g of water; example release rates 0.4, 1.0 and 2.0 g/day show arithmetic only. Working practices: 3 bottles per arm, 3 reeds per wicking glass, climb marked at 15 min, 1 h, 4 h, 24 h, 3% mixing allowance, weighing on days 0, 3, 7, 14, blind 0–5 house scale. CSI's base pages state: soft florals (lavender, jasmine, rose, peony), powdery/musky and light gourmand (coconut milk, vanilla milk); 10–30%; rest 24–48 hours (Softness); neutral, "no added fixatives, no complex enhancements", for all fragrance families; start at 10%, up to a maximum of 30%, 20% recommended, typical working blend 75% base + 25% fragrance; rest 24–48 hours before bottling; "flip reeds after the first hour" (Pure Performance). CSI publishes no composition, density, viscosity, evaporation rate, flash point or shelf life for any reed diffuser base; no throw, evaporation or longevity data for any base, oil or reed; no reed diameter; and no neck size or fill line for the Gold bottles. The five base pages are differentiated only by the fragrance families they say they are for — that is a starting point for a test, not a ranking. CSI sells fibre reeds, not rattan. No IFRA percentage for any oil is stated here: the Category 10A limit on the oil's own IFRA certificate (ask CSI on WhatsApp) applies alongside the base page's 30% maximum, and the lower of the two wins. Costs exclude labour, labels, boxes, freight and GST. Diwali 2026 falls on Sunday 8 November.
