Biozym Fish Tank Scale Cleaner is a non-toxic cleaning formula that quickly dissolves the white scale and stain build-up that ages an aquarium — on glass, heaters and thermometers.

Scale film clouds the view and insulates heater elements. Apply the cleaner, let it work, rinse and put the equipment back, and the tank looks like it just left the shop. It is non-corrosive and gentle on hands, so it is straightforward during a routine clean.

Good to know:
– Removes limescale, hard-water stains and calcium build-up.
– For use on tank glass, heaters and thermometers.
– Non-toxic, non-corrosive and safe for fish.
– 500ml bottle.
