Hey all, i just got a fluval 2 plus underwater filter.I am thinking that i will put it in my 4ft when i get it.i've forgotten what you guys call when you have a tank under a tank a sump i think any way wheen i put it in my 4ft how do i make a sumpy thingy.i think i'll make my 4ft a discus breeding tank or something.

4ft for a pair of discus ?

is that too big?

A pair of discus need about 30 gallons .. babies would need the 4ft though

i was told that a 4ft is good for discus breeding.

You could divide that tank in 2 and make 2 breeding tanks from it but make sure you have big tanks for the babies to grow out.
