FritzZyme 7 Live Nitrifying Bacteria Naturally Removes Amonia & Nitrite for Freshwater Fish (16-Ounce)

I bought this product after seeing multiple reviews outside of Amazon saying that this product worked very well to start an aquarium with fish instantly. I confirm it works this way!! I had an emergency to relocate 10 white cloud mountain minnows cramped in a 5 gallons who were fighting too much. So I bought a 10 gallons and filled it with remineralized RO water, I did not even had a filter for this new tank, so I tossed a filter sponge, a bit of drift wood and a USB water pump just like that. Then I poured the recommended dose for a new 10 gallons tank and I did no see any alarming ammonia or nitrite spike, only once in 2 weeks had I have to change the water due to a minor spike and it has been a month now that the 10 gallon is up a running (with a filter, substrate and plants now). I did not lose a single fish. I highly recommend this product.

I've had a major cycle crash in my 10 gallon and nothing I have done had been helping. I have used this brand before to help me cycle and it worked great. This cycle crash has forced me to do major water changes every day for weeks. I ordered this brand again because it worked last time, and it arrived last night (took a few weeks to arrive, which is the big downside). However, I dosed it last night and tonight? Normal ammonia and nitrite levels for the first time in about 3 weeks. Thank god for this product

Brilliant

La tapa de la botella está partida a la mitad y le falta un pedazo como si hubiera sido enviada así intencionalmente

Item was delivered 2 weeks later than originally stated and had no lid. Not cool.
