Korelia evolution or korelia #2

[bubby317]

Ok help,
Do you think that a 750 gph power head would be too strong for my little 20g L tank? The PH I'm looking at is the Korelia evolution, will it be too strong of a current? Or should I just go with the korelia #2

Im only going to be keeping 2 clowns, and a clean up crew. 20 pounds of LR and a HOB filter for surface disturbance.

I think youll be fine.... My frag tank is 20g and a single koralia #1 wasnt enough flow. I have 2X koralia #1 (one on each end) and IMO its still lacking
