I have a nice 5 gallon fish tank....or maybe it's a reptile thing. I don't know. Anyway, neons are really cool. I want to put 300 in there and the dealer said he would toss in some Angelicus Catfish...which are cool too! And then I figured I would need a decent filter, so I figure I can pump the water out with a big Eheim unit...though a series of coffee filters....and then into a 100 gallon sump...with an Iwaki return pump in there...something like 1200gph give or take.
My question is:
Should I use three 200 watt heaters or four?
Oh...and can I just use table salt in the water??
