Powerheads

I'm looking for new power heads for my 30 gallon reef tank. What size and type of pumps is recommended? Should I do two smaller ones or one larger one? I have a hang on the back sump and refugium so they add additional flow to the tank.

I've been researching this one myself. I can't give you any advice based on my experience, but I can impart what I've found - keep in mind I don't know how reliable this info is. It seems to be a general consensus that several small power heads are better than one big one. I also read an article that said you should have water flow 30 times the volume of you tank with FOWLR and 50 times if you have a reef tank with demanding coral. So in your case two 750 gal/hr power heads should be good - if not overkill. I'm shooting for 35-40 since I have no plan to keep demanding coral, as I don't have the expertise to keep them alive anyway.

I'd go with 2 Hydor Nano 240s

I think a good set up would be a jebao wp10 and then a small cheap circ. Pump towards the back of the tank to help stir up detritus behind the rock work

Powerheads

Just chiming in because I want to better understand the topic. Is the goal of high turnover and circulation in a SW tank:
A. Eliminate dead spots; ensure that any debris becomes suspended and eventually drawn into the filter
B. Keep the LR and LR inhabitants happy
C. Both A and B
Also, here is a similar thread on the subject: Detritus problem

I was actually looking at doing the hydors or something along those lines.
And I would say the goal is to eliminate those dead spots so there isn't detritus and areas that could be problems. Plus it helps to keep the livestock happy. The goal with any tank in my opinion is to make as much like their natural systems as possible.

I just bought two hydor 850's for my 55 gal tank. Figure if it isn't enough current I can always add later. drsfostersmith.com has a sale going on them right now. The 850's are $28. 1150's are $31. Lowest prices I've been able to find. (The 1150's were on the shelf at my LFS for $59.99!)

That eBay pump is not a brand name pump. Who knows what you're getting. Why can't you just let me have my victory?

I run those pumps. Love em. Run just as well as the Hydors. just try and stay away from the ones with the scution cup, those pretty much go bad really fast. the ones with the magnets are good. I still run them today.
