On Wed the tank was good but wed night it becaume couldy and thursday it is bad. I am running a MAG 350PRO for a filter and i have added some Stability from Seachem into the tank! The first time i have set up a tank it was couldy for a day and that was it , what is going on ? can i get some help? whatsup227 2009-03-26 http://forum.aqua-fish.net/?topic=couldy-water_#2 sounds like a bacterial bloom, its part of the cycling process. It should disappear as soon as the filter has built up a bacterial colony to deal with it mickey 2009-03-26 http://forum.aqua-fish.net/?topic=couldy-water_#3 thanks whatsup227 2009-03-30
