Thanks so much for the non-judgemental feedback! I say that because I did talk to a seller of RHP's (tho not about this question) and was somewhat chastised for using aquariums. He was of a mind that I should already have my custom-made PVC cages. For me, that's a couple months off yet...

Gonna hook it up today, give it a chance till Sunday for outgassing, then test it on my smaller, unoccupied tank so I can get temps right before moving it over my little girl.
