circulation question

[wjake]

I have a bare bottom 30 cube i am starting with about 30 lbs of rock in it. how many Powerheads would you guys use for circulation and which ones are great but inexpensive for this size tank? GPH etc?

also anyone have any for sale?

How is the water filtered and returned on your tank? You could play around with some angles on that. Check into the koralia powerheads for good cheaper flow. Depending on your coral needs look into the 2 and 3

I have a Red Sea Max, it's a 30g cube and I use the Koralia 2 and the corals love it. I tried the Koralia nano first and I wasn't getting enough circulation in the tank. I shut the pumps off to feed the fish and corals and it helps to have a good powerhead to keep things flowing until the pumps come back on. Plus I have my Koralia pluged into a battery backup just in case the power goes out (and it has saved me several times) Hope this helps you to decide.

I have a CPR Bak Pak on the tank for my filtration and it works great, i have it modded a bit and previously before i set this reef up (about a year ago) i had it running on a FOLR tank and it kept the water prestine
