Thanks man, I have a 250 watt stealth that came with the tank but it looks pretty sketchy. Don't think I'd be comfortable using it for anything other than fishless cycling. I was thinking of going by that place you mentioned for the $30 titanium heaters with controllers? Those sounds sweet.
I might take you up on the hydor, although I'm a little tempted to try my own stability experiment 100% from scratch, but maybe it's for the best to use all I can.
As to the setup:
Tomorrow I will get substrate, heaters, fill the tank up again (drained it), and get the FX5 running. Pictures to come.
