Would it be better to run 1 200 gal/hour pump, or 4 50 gal/hour pumps? The specific number of gallons are arbitrary. I am just trying to ask if you want one big one or a bunch of little ones.

2 medium sized ones are best, 4 small ones are a waste of money, 1 big one might not get the whole tank, 2 medium ones are best, one on the left side blowing indirect current to algae/rock/corals while you can put the other one on the other side at the top of the aquarium to get good oxygen tansfer

Good to know. Are there any "low pro" powerheads on the market or a way to keep them out of sight while still allowing them to do their job? I'd like a natural looking tank, and in all the discovery channel programs that I've seen, none of them had a powerhead in the reef documentary...

you can hide them behind rocks and stuff, they are ugly but do the job, if you dont like the look then just get 1 big one and place it at the back corner of your tank.

thats the thing with t.v., they get things to look better than they are. its just kinda something you have to deal with. And its best to get the best powerhead you can, with good water flow.

I run three @270gph in my 150. PLENTY

Hahaha really? I run almost 4,000 GPH through my little 75g SPS dominated tank. The more the better. Promise. I've seen many members complain of algae problems and it was almost always attributed to to low a flow in their tanks. For a 150g I'd be recommending 3 Tunze 6060's to create cross linear paths at 1,600 GPH each.

Including the water flow from my return pump I push close to 3600gal/hr in my 120gal.

Movement is key to a tank, you want your water to cycle, keeps the fish happier too, try off settign them if you can, half them switch a few times a day to get a real realistic effect. Thats what i do in my 55 gallon. I got 2 400GPH in my one tank switching ever 6 hours or so to change the flow of water. While i got the rest of the pumos cycling the water from side to side. IT is a sick setup, i will take some picks.

As for hiding. I put them behind some large rocks in the center hooked to my endergravel. One facing each way. Cant even see them.
