After 12 weeks of use, tank looks the same, worthless. All affected corals were removed from the system and eventually died. It smells like sterile water honestly.

Api has my loyalty. Keeps my betta fish and tiger barbs safe & limits toxic ammonia and nitrate. A must when setting up an aquarium.

Nitrite levels can spike within just a few hours during certain stages of cycling and kill fish instantly. Dosed according to instructions after added ammonia as 'food' for the bacteria.

If using quick start, be prepared to wait 2 weeks before your tanked is cycled.

Whatever is in this product is deadly to freshwater fish at least. If i was lying it surely would not be for a lousy bottle of fish neutralizer.
