Zoo Med Hermit Crab Drinking Water Conditioner
Tap water is not safe for hermit crabs until it's conditioned. Zoo Med Hermit Crab Drinking Water Conditioner is a 2.25 fl oz (approx. 66 mL) dropper bottle that neutralises chlorine and chloramine and adds back electrolytes, making ordinary tap water safe for a land hermit crab's fresh drinking bowl. Dose it every time you refill the dish.
Key features
- Neutralises chlorine and chloramine — removes the two additives in most mains water that irritate a hermit crab's gills.
- Adds back electrolytes — replaces minerals stripped out by the dechlorination process.
- Dropper-dosed — 2 drops per 8 fl oz (approx. 240 mL) cup of water, so you dose to the bowl you actually use.
- Fast-acting — water is safe to use within moments of dosing, no standing time.
- Small bottle, long life — each dose is only a couple of drops, so one bottle covers many bowl refills.

Dosage and directions
Measure the actual volume of your crab's fresh water dish rather than guessing, then add 2 drops for every 8 fl oz (about 240 mL) of water. Dose fresh each time the bowl is refilled or topped up — the conditioner does not have a lasting residual effect once the water is used or evaporates. Zoo Med doesn't publish a total treated-water yield per bottle or the drops-per-millilitre for its dropper, so a per-litre cost figure isn't shown on this page — publishing one would mean guessing at a number Zoo Med hasn't stated.
Suitable for, and not suitable for
Suitable for the fresh drinking and bathing water of land hermit crabs (Coenobita species). Not a substitute for salt water — hermit crabs need both a fresh bowl and a marine-salt bowl available at all times, and this product is not formulated or dosed for the salt water side. Pair it with Zoo Med Hermit Crab Salt Water Conditioner for the salt bowl.
Goes well with
- Zoo Med Hermit Crab Salt Water Conditioner — the matching conditioner for the crab's salt water bowl.
- Zoo Med Hermit Crab "Bright" Water/Food Bowl — a dedicated dish to dose into.
- Zoo Med Hermit Crab Sea Sponge — soaks up conditioned water and holds humidity in the crabitat.

Common questions
Can I use this in the crab's salt water bowl too?
No. It's formulated and dosed for fresh drinking water only. Use Zoo Med Hermit Crab Salt Water Conditioner for the separate marine-salt bowl every hermit crab also needs.
How often do I need to dose?
Every time you refill or top up the fresh water dish, since the conditioner treats the water present at that moment rather than protecting water added later.
What happens if I forget a dose?
Untreated tap water can carry chlorine and chloramine that irritate a hermit crab's gills, so it's worth conditioning every refill rather than skipping doses.
How many drops does one bottle contain?
Zoo Med doesn't publish a total dose count for the 2.25 fl oz bottle, so we can't state exactly how many refills it covers — only the per-cup dose rate above.
