Hey Wrassman...I am Glad to read that your tank is stable now. You also stated in your last post that you recently switched over to seachem additives. I have read many good things about seachem products. Is it also possible that the reason that your tank is now stable the result of the seachem products? I see that all your tank parameters are great. Would this also be the reason for a stable tank? Do you think if you disconnected your eco-aqualizer that yout tank would become unstable again? That would be a great test for you to do to see if things reverse.
