View Full Version : FOWLR Flow

03/30/2011, 07:43 PM
Coming from the reefing side of things, I'm used to HIGH flow with (expensive:worried:) powerheads like Vortechs and Tunzes.

However, I'm not doing that on my 90 FOWLR. I'd like to use the newer Koralias, but have very little experience with them first hand.. would two of the Evolution 750's work, or am I looking at 1050's or higher? (lower?)

Fish are going to be active like Tiggers/damsels/tangs/etc etc (not sure yet).

might be able to get by just with your return pump

My return pump is on the low end.. probably 3x turnover per hour. Maybe 4x. I like it better that way though.

I personally would go with at least the 1050's maybe 1400's.....My thinking and I may be wrong is the flow in the ocean is the same weather or not the coral is there.

Oh you're right on this.. I think getting sufficient turnover in a FOWLR is important as well.. have to get all the detritus into the overflow box and down to the sump so it can get skimmed out.

My question is more about the Koralias really. I don't know what they are equivalent to.

In my 180 FOWLR (72x24x24 with one over flow) I have a 1100gph Return with a Koralia 4 (1200gph) and a new Marineland Maxi Jet 1000 Prop setup (new design is closer to 1000gph) for returning flow facing my overflow. I want as much water as I can to get cleaned so I have a lot of emphasis on under tow for uneaten food to circulate and if it floats long enough it will get sucked back down to my filter sock. If it hasn't been eaten with in minutes then it doesn't belong in my display.

in my 40g breeder i use for my QT tank i have a evo1400.

at the very minimum i would go with at least 1 evo1400. probably two if i had a 90g.

two can be had for less than $100 new.
