I think 17 may be overkill. Try 13 or 14 slaved together on short pulse mode with a half second in between each pulse. Or, a couple of K2s would have the same effect.


It really depends on what you're keeping, actually. SPS like a lot more flow, while a FOWLR wouldn't need nearly as much. Mixed reef would call for a decent amount of flow which you should be able to get from the two Koralias.

i have softcorals and fish just trying ot keep the algea down

 

[dakota9]

2 Koralia 3's or 4's
or
1 Tunze 6025 modded

If you were going with SPS, I'd say more, but with your bio-load, anything more would be over kill

Oh, ..........IMHO
