how many gallons should I cycle through my 72 gal. saltwater tank per hour

[Saga]

I have slot of red slim. I think I may need more water flow. Right now my return pump does around 720gph.

thats a good flow

for FOWLR you want about 10x once you go reef it can be alot different and some corals can require 30-50x the flow rate

Thanks. I want to do coral. I'm going to get two 1050 gph powerheads to help with water flow.

[Gti_Leo]

i'd look into getting two 750gph korallias for now, and if you need the extra flow you could always add another

[Saga]

I was going to get the korallias 1050, but u say the 750 will work. What is your opinion on hooking the two korallias to a wave maker? Do you suggest any. Some not to expensive. I know some go for hundreds.

[Gti_Leo]

no clue never used a wave maker.

you could always use a timer on each powerhead

I bought a power strip on eBay that alternates two of the plugs with a timer for 50 bucks, I used two of the korillia #8 units at 3300gph to alternate on and off every 90 seconds. This produces a very natural surge effect that the corals are loving. Tank is 300 gallon.
