Newbie need help - Flow Question.

I agree ^, but personally I like about 6-7x turnover through the sump compared to a lot of peopl who have 10-20x or more through their sump. Then use powerheads and closed loops to get the flow in the tank that your corals need.

Ya, I also only have about 5x thru my sump. Let's the skimmer and carbon do it's thing. Ideally the flow should come from power heads or closed loop, as already mentioned.

I am doing that way too
As being recommended, I'll upgrade my returns (3 pumps.) Right now 165GPH
to be about 320GPH each (at the out-puts in the tank ).
But besides, I talked to my uncle in LA, he'll ship to me 2 of the Tunze ( He's reef guy so he will know what to buy for my tank

So after upgrade, my return rate would be 950GPH = about 5 times turnover

But flow will be very strong, around 1800-2000GPH as he mentioned.

I dont want to go for strong return and so, as you said, the skimmers will be useless.

Thanks,

What is the dimension of this tank? 2000gph is still pretty low for a 170g SPS tank. Personally, with a tank that size, I would probably go into the 10,000gph range.
