> 3 dayTried it out on a brand new tank and additionally into a existing tank, I have been having wonderful water quality since then in both tanks. I would recommend a activated carbon filter with this product to take full advantage of the colony

> 3 dayI didn’t do a technical test but I set up a lot of aquariums with fish in and sterile-start. I was impressed that shortly later I had an overstocked tank, no casualties, and no nitrogen.

> 3 dayCycled my tank in a matter if three days! All my Ammonia , nitrite , and nitrate. Were all at 0ppm! This is a nitrifying bacteria (helps kill Ammonia Nitrite and Nitrate) . This is NOT BENEFICIAL. If you want Beneficial (helps clean sludge in filter and tank) get fluval waste control.
