Seachem Axolotl Conditioner 250ml
Tap water made safe for the most ammonia-sensitive animal in the room. Seachem Axolotl Conditioner is a concentrated water conditioner formulated for axolotl tanks. It removes chlorine and chloramine from tap water and detoxifies ammonia, nitrite and nitrate. One 5 mL capful treats 160 litres, so a 250 mL bottle covers roughly 8,000 litres of water changes.
Key features
- Removes chlorine and chloramine — both are used in Australian mains supplies, and chloramine does not gas off if you leave a bucket standing overnight
- Detoxifies ammonia — converts it to a form that will not burn gills but is still available to the bacteria in your filter
- Detoxifies nitrite and nitrate — which is why it earns its place during a cycle, when the spikes do the damage
- Binds heavy metals at the concentrations found in typical tap water
- Non-acidic — it will not pull your pH down, so it can be dosed without chasing the reading afterwards
- Concentrated — 5 mL per 160 L means a 250 mL bottle outlasts a year of water changes on most axolotl tanks
- Under 1c per litre — worked from the standard dose across the full bottle, this is the cheapest way to treat water for axolotls, size for size

Dosage and directions
One capful is 5 mL. Each thread on the cap holds roughly 1 mL, which is how you measure a dose for a tub or a hospital container.
| Water volume | Standard dose |
|---|---|
| 40 L | 1.25 mL (about one cap thread) |
| 80 L | 2.5 mL (half a capful) |
| 160 L | 5 mL (1 capful) |
| 320 L | 10 mL (2 capfuls) |
How far a dose goes
| Situation | Dose | What it achieves |
|---|---|---|
| Routine water change on chlorinated mains | Standard — 5 mL per 160 L | Removes chlorine and chloramine, detoxifies the ammonia chloramine releases |
| Heavily chloraminated supply | Double | Covers the extra ammonia load; a double dose is safe |
| Nitrite spike during cycling | Up to five times | Detoxifies nitrite while the biofilter catches up |
Add it to the new water in a bucket first, or dose for the full tank volume if you are adding it straight to the tank. Detoxification is temporary — it buys the biofilter time rather than replacing one.
A sulfur-like smell when you open the bottle is normal for this chemistry. It is not a sign the product has spoiled.
Suitable for, and not suitable for
Suitable for: axolotl tanks and grow-out tubs · any freshwater aquarium on chlorinated or chloraminated mains water · new tanks during cycling · emergency ammonia and nitrite control.
Not suitable for: marine aquariums · use as a substitute for a cycled biofilter · masking an ammonia source you have not found · use as a pH adjuster, since it deliberately does not move pH.
Ammonia test kits can read differently for a period after any ammonia-binding conditioner is dosed. Test before you dose, or use a kit that separates free ammonia from total ammonia.
Care and storage
- Replace the cap firmly — the dosing threads are the measure, and a crusted cap is hard to read
- Store out of direct sunlight, at room temperature, out of reach of children
- Shake before use if the bottle has been standing for a long period
Goes well with
- Seachem Axolotl Buffer — holds pH steady, which is the one thing this conditioner is designed not to do
- Seachem Stability — the bacterial culture that does permanently what this product only does temporarily
- Seachem MultiTest: Ammonia — tells you whether you still need the emergency dose
- Seachem Ammonia Alert — an in-tank badge that changes colour on free ammonia between tests

Common questions
How much Axolotl Conditioner do I use per litre?
The standard dose is 5 mL — one capful — per 160 litres, which works out at roughly 1 mL per 32 litres. Each thread on the cap holds about 1 mL for smaller volumes.
Can I use it in a tank that already has axolotls in it?
Yes. Dose for the full volume of the tank when adding it directly, or treat the replacement water in a bucket before it goes in.
Does it remove ammonia permanently?
No. It converts ammonia to a form that is not toxic to the animal but is still available to the beneficial bacteria in the filter. The effect is temporary, so it supports a cycling tank rather than replacing a biofilter.
Why does the bottle smell like sulphur?
A sulfur-like odour is normal for this chemistry and does not mean the bottle has gone off.
Will it change my pH?
No. It is non-acidic and does not shift pH. If you need to hold pH steady for axolotls, use a dedicated buffer alongside it.
Can I use it on a tropical freshwater tank?
Yes. It is a freshwater conditioner and can be used on any freshwater aquarium at the stated dose.
