hey everyone. i just recently moved my aquarium tank and after the first couple of weeks hairy green algae has covered everything. so i checked phosphate n there isnt any, no nitrate, nitrite n 0.01 ammonia.. no idea wat to do???? please help.
You also killed off everything good - not only the filtration bacteria, but also all/any microscopic animals in the sand. These animals could/did help with filtration by eating detritus, and even algae.i didnt put the water back in the tank i cleand the sand then tipped the water out and put the sand in the sun for a day to kill anythin bad.
