Keeping fish will never be the same again! Wattronix introduces the HappyFish™ Filter Systems. This is ...THE... Filtration System for the 21st Century. HappyFish™ compliments the standard freshwater biological filter system which turns Ammonia released by fish into Nitrite and Nitrate.

Nitrate, accumulating over time, will stress fish and make them susceptible to disease, will eventually kill them and inverts too, will reduce or prevent coral growth and will encourage a lush growth of green algae. Now with the addition of the HappyFish™ De-Nitrating Below Sand Filter system, every pond can benefit from the conversion of harmful Nitrate into harmless by-products. Ponds with HappyFish™ installed have undetectable levels of Nitrate after only a few months of use.
