ok here goes i set my tank up back in early june, unfortunately for me i didnt know anything about "fishless cycling" i wish i did because i woulve have done this, instead i have my tank with some amazingly hardy 3 gouramis, and 2 platies, and 2 mollies, ok so i constantly perform water changes, for about 3 weeks now my amonia has been 0 but my nitrite for a while was at 2.0 so i was doing daily or every other day 10-25% water changes, then one day i did a big 75% water change as i was getting fustrated, a few days later i checked my water and my nitrites were down to .50 i also got a very cloudly tank for a while with what looked like a milky substance, so i assume this was the bacterial bloom ive heard tons about, my nitrite then went to .25 - almost gone it then went back to .50 so i did another 75% change then went back all the way to 2.0 after what appeared to me as a week where my fish were moving their bowels continually i'm not sure if this has something to do with it - i dont even feed my fish often, once every other day as i was adivised - so i have now done another 75% water change, hoping this will finally complete it's cycling cause it seems everytime i do a big vchange i come so close to being there n then lose it,??? woul it help if i got some water from a friends established tank and put it in my tank with my next water change hoping to get some of his good bacteria??? assuming his tank parameters are ok??? or am i almost throuhg with this??? what shoul be my next step??? by the way i have a 20 g
