Aquarium Water Treatments

Healthy fish start with healthy water. Tap water contains chlorine, chloramine and heavy metals that can harm fish, so a good water conditioner is essential every time you set up a tank or top up with fresh water. Our range also includes bacteria starters to help establish your filter, clarifiers for cloudy water and treatments to keep algae under control.

The best way to know what your water needs is to test it regularly with one of our aquarium test kits, so you can spot problems early and treat with confidence. Combined with regular partial water changes using the tools in our aquarium maintenance range, the right water treatments will keep your tank stable, clear and safe for your fish. Ask our aquatics team if you're not sure where to start.
