Any problems with heat fluctuations? Are you running carbon? After the water changes you mentioned, did you see an immediate improvement, or a decline in your tank over all?

[ganowicki]

no problems with heat fluctuations. i am running Chemipure carbon. I don't notice any immediate improvement or decline after a water change.

How old is the system? Is it a barebottom system? I've heard of tanks getting wiped out because someone disturbed their old sand.

Anything leaking electricity into the tank? Copper poisoning?
