Koralia 1050

I have Two of these in my 65gal tank. Is that too much flow?

 

Nope. I have 2 1400's, 2 750's, and a 450+ Return in my 84 gallon. Just position them to give you no dead spots...and if you can't, get another Powerhead so you can achieve this.

 

depends on what you have for rockwork, sandbed, fish, corals, etc.

With 2100 GPH + say 600GPH for your filter = something like 2700GPH which is about 41.5 turnovers/hour if your total system volume is about 65 gallons. That is acceptible for any soft corals (some you may have to find slower/lower flow areas on the sandbed for) and most LPS corals if not all LPS.

This is still not quite enough for SPS tho.

 

Thanks for the replies I will leave the powerheads in I plan on doing mostly LPS and soft coral because I have T5 lighting. It kust seems like my fish are hiding now that I added the flow.My Clowns do not seem happy.
