This thread is pretty old but i thought i would give everyone if anyone is still following a update.. I talked to my lfs retailer ( very good connection with ) and she studied at the shedd aquarium in chicago before becoming a fish store owner and she talked to her buddy and gave me his number ( havent called him yet since today was my first day at the fish store in months since work has been crazy busy and they close at 5) BUT ANYWAY she told him everything i described and he actually had the same instances happen to him in his early years.. Hoping to make good ties with this guy since my 75 gl has been dorment for 3 months i have started stocking again ( 2 true prrcula clowns, 2 yellow firefish and 1 bi color angel all in qt right now with copparsafe) still having issues with my 100 gl and im thinking of selling it for something without a over flow since its been a pain in my A$$
