flow for 20 gallon long sps tank

[Shane52]

I just bought two hydor koralia pumps that are 425gph. So a total of 850 gph. Is this enough flow for my tank to keep sps?

i also have a wavemaker to attach the two pumps to

anyone?

I say no. I had those in a 14 gallon biocube and it was barely enough. I'd consider getting an mp10, and put the koralias on the other side.

i'd aim for 2 powerheads. both right around the 1000gph mark. koralias are nice beause they have a wide flow pattern. tunze nanostreams would work well also.
