Experimenting with flow. I have a 37g (30x12x22) mixed reef asnd for a long time used 2 MJ900s for flow (one at each end pointiong to the front center. Recently tried MJ1000s with the hyder-flow attachment. Good circular dispursement, but one has gummed up after 2 weeks.

I'd like to try the koralias, but which to get, how many and placement.

Can anyone with a 37 or 29 gallon advise?

Thanks
 
I have a 36 gallon bow with 2 Koralia 2's in it and a 4gph return. I shoulda got two 3's or really I shoulda gone with Tunze.
