Right now Ive got a whisper(200gph) and two marineland (100gph each) on my 20 gallon with the brichardi's. I am deffinatley going to loose one of the marinelands, but i could loose both of the smaller ones and be ok gph filtration wise, but with the rock work I am a little worried about dead water.

Adding to this, when they start spawning, my guess is the fry will be spending about all there time on the bottom, and I really dont want an intake tube close to the fry or there wont be fry for long. So how could I ensure that there isnt dead water, with out over swiming or sucking up the fry?

Would the whisper filter alone be enough to provide sufficent circulation?
