Well my nitrates are at about 20 now. Is that ok? All my system stuff is in 'my info'. I think part of my problem might have been not cleaning the substrate..... I didn't know how or that I was suppose to until the last pwc
:| I think another problem might be that I was out of state for 6 weeks and I tried to explain to my mom how to do a pwc
, but she informed me tonight that she only did one because it was too much for her..... so could that be another cause of high nitrates? So how long should I wait to add the kole tang? in a week if the nitrate levels seem to be stable?
