Flow Rate
 

So I went out and purchased 2 Koralia Evolutions (1400gph) for my 50g based on the recomendations of a lfs. Just in the middle of cyling my tank, and I am just doubting if it is to much flow in the main tank..... Also have a sump that is rated at 230gph max, but don't think that is based on the 4' calculations. Am I going crazy?

Flow rates, patterns and sump turnover are widely discussed topics. A search on here usually turns up some good information. Or cruise the tank journals. Is it a premade manufactured sump or just a tank with some baffles?

is your tank only 3' long?

those evo's will be pushing alot of flow

By calculations that's just a hair over 60X turn over.....so if your doing an SPS tank that would be fine

what are your coral plans?

The sump is a modified Oceanic Trickle Filter, with one baffle put in it.

The tank is 3' long.

I am doing a mixed reef, which include some SPS and other corals. Basically I am shutting down my 25g tanks that is currently setup and moving everything over to the 50g.

Thanks for all the responses, I appreciate the input.

IMO those 2 HK will generate too much directional flow for your tank. 4 HK 750gph or HK3 (850gph) will be better.
I know how much flow a HK generate because I have both HK 1400gph and HK3 (850gph). The flow is not that wide unless you mod it. That's another story.

That's ruffly what I was running on my 55 before I upgraded to the 90...and it was a little tricky doing a mixed reef.....but if you spend a wile getting the flow set up just right you should be fine.

Well, since they are already in the water, nothing I can do about returning them....Lets hear about this mod.....

I am interested in the mod as well. I have 2 koralia 1050 in my 75 and they generate too much direct flow and I want something wider.

Is this mod for the Evo's or the old models?
