Evolution Aqua PURE Aquarium Freshwater Bacteria Bio-Balls – 250 ML

Great Product! I was having issues with my tank having spikes and mini cycles and always staying a bit cloudy. This is even with water changes, ect. I tossed some of these in and with in 3 days my tank was crystal clear & has remained so. However, I do keep up my daily cleaning & water changes as I have discus.I have started cycling a new tank with this & some old media from my other tank. Because it’s a 90 gallon tank I put in the whole little jar of it & some stability. By the next day I put my dither fish in and they have been doing fine. It is only slightly cloudy right now. But, again it hasn’t been 3 days time for that to clear up.This stuff is so good that I try to keep at least 2 extra jars at all times on me.
