Flow required

[mvickramm]

Can you please tell me how much flow is required for a 75g FOWLR tank?
THanks,
Vick

As much as you want. IMO, on a fowlr you should have at least 20x turnover. The fishies will be happy with more and it might cut down on nuissance algae a bit to up the flow. Keeps the fish waste/detritus in suspension longer so your skimmer has a chance to get rid of it.

Depends on what you intend to keep, soft coral, LPS, SPS each have their own flow requirements, and even within each group there are variations.

30x turnover is probably a pretty good place to start. So a minimum is in the neighborhood 2500 GPH, bit its also important that there arent any dead spots.

A 75 gallon FOWLR should be fine with 20x (or 1500gph) but it does depend on what you want to keep. Busy shoaling fish like chromis or anthias like high flow areas and will hang out in the water column all day. Seahorses on the other hand, will get wrecked with that much flow. I'd say that 20x is a good place to start, and you can always adjust accordingly later on.

2 tunze 6025s will be fine for your tank, 1 each side and half way down pointing slightly at the top, will be more than enough flow for your 75 fish only

Thanks for the reply guys,
I have a 1000gph return pump. So if I buy a koralia 3 (850gph) will that be good enough?
Thanks,
Vick

Sorry I missed the FOWLR part somehow. Agreed with the above.

You have a 1000GPH return pump, but how much of that flow is going through the tank? If you have all of it going through then you should be fine with the Korallia 3.

Definitely, did you factor in head pressure loss on your return pump? You’ll come to find out that it will be substantially less.
