Hey guys I am looking at buying powerheads for my 120 reef. I am mainly a softie, LPS type guy mostly any coral that sways. Anywho I was looking at buying 2 Korilla 850s do you think that would be enough flow. I already have a 1500 flow return pump.
I've got 2 mp40's (bought used) and a Koralia 950 in my standard 120. Just some small frags in my tank so far though. The mp40's are currently set to about 40% power.
