Fish Science Tap Clean

Fish Science Tap Clean is a complete water conditioner for freshwater and marine aquariums, designed to make tap water safe for fish instantly. Available in a range of sizes to suit tanks of different scale, it handles the chemistry of every water change so your fish don't have to.

Immediate Tap Water Treatment

Tap water in the UK contains chlorine and chloramines — both harmful to fish and aquatic life. Fish Science Tap Clean neutralises both on contact, making tap water safe to use straight away without waiting. It works for both freshwater and marine aquarium setups.

Aloe Vera for Fish Health

The formula is enriched with Aloe Vera, which supports gill health and helps maintain the mucous membrane — the fish's natural protective slime coat. This is particularly useful during water changes, when fish are most vulnerable to stress and physical irritation.

Reduces Transport and Water Change Stress

Beyond dechlorination, Fish Science Tap Clean helps fish settle after disturbance. Whether you're introducing new fish or carrying out a routine partial water change, the formula supports a calmer transition back to normal behaviour.

Natural Humus for Environment Recreation

Fish Science Tap Clean also contains natural humus, which can help recreate the water conditions of clearwater or darker, more tannin-rich natural environments — useful for keepers working with species that benefit from specific water chemistry profiles.

Dosing

Dose at 1ml per 4 litres of water. Use when setting up a new aquarium or during any partial water change. Choose the bottle size that suits your tank volume and water change routine from the options on this page.

Fish Science Tap Clean keeps water chemistry straightforward, giving keepers one reliable product to reach for every time the tap goes on.
