If the intake is just the overflow box how will it chew up the anemones? Overflow is synergy ghost overflow. If I can push 1200-1600gph through the overflow would it work? I want to keep BTA.Close loop is really bad for anemones, not the way to move water in anemone tank for sure. The intake will really chew up anemones. I would use one of the low power propeller type PH. I like Vortec, but any of the propeller type PH combinations set at the right place will do.
What kind of anemone do you want to keep?

I think you are confusing a closed loop with just a normal overflow system. Running your overflow very fast can cause a lot of flow. But the flow won't be as random as say the overflow + a power head. For a bta just the overflow with a large pump and high turnover rate you may be alright. That is if the current isn't so strong that if the nem let's loose it goes into the overflow.
A closed loop is drilling another intake below the water line plumbing it to a pump and then plumbing it to more returns. So it basically sucks display water out and pushes it back into the display. The intake on this system like Orion said will murder nems.
For BTA, flow for LPS should be fine. I use a lot of Vortech PH, just turn dow the power is all I need to do. Some of the older PH, point to to a wall or surface, or against each other. Any of these three methods can broaden the flow and make it more suitable for anemones.I know this is a general sort of question, but can you elaborate on what you think the "right" place is for PH's in a BTA tank? Being less flow demanding I would imagine they do better away from a direct stream but not sure about flow patterns beyond that. Anything in particular that can be done in the overall setup of the tank or placement of the PH's to decrease the chance of an anemone coming into contact with them?
A lot of flow will created more noise. Also more energy and heat (may not be too important with a small tank)Yeah my mistake I just meant pushing a ton of flow through overflow. The plan is the ghost overflow with 2x 3/4" returns with flow converging in the middle of tank to create turbulance. And if that wasn't enough I was going to put flow accelerators. The tank is small so was hoping 1400gph or so would be more than enough.

Back before the Propeller, low power type PH become available, I used high return and large close loop for circulation for my 450 gal tank, using several pumps that use several amps each. 24/7/365 running these pumps generated a lot of heat and use up a lot of power.
more uniform flow that doesn't blast the anemone but still creates substantial turnover of water on the nems oral disc which keeps the nem happy by facilitating the exchange of water for hydrostatic pressure and carries away expelled waste.
