Small anemone only tank with only overflow

[gus6464]

I have a small nano setup that I want to put in my office for just BTA and nothing else.

Display tank - 24x15x16 ~23g

The tank is not drilled yet but I only want to do it if I can do BTA without having wave makers or power heads as they have all killed the anemones I have put in my main tank in the past. I want to be able to get away with just having flow from the overflow.

Because of this I am considering using the synergy ghost overflow or the modular marine one with dual 3/4" returns. If I can push 1200-1500gph through the overflow would that be enough flow for BTA? I can add flow accelerators on the returns if need be.

Another overflow I am looking at is the eshopps eclipse overflow in Large as the box is smaller but it says it can do 1000gph max.

its all laminar flow is the problem. Not the GPH or power. If you Y or T the return and force them against each other(create turbulance) it should work

I would say thats over kill on flow for a 23gal....my 30 had a 700gph return with btas and no power heads. Ive since added a 465gph power head and reduced the flow from return dramatically to add contact time in sump....

That's what the plan is. Put the two returns on the back ends of the tank and point them at each other towards the middle. I figured the turbulence created by jets meeting would be enough. So you think I can get away with the eshopps overflow which is 1000gph?

id still use the rule of thumb. total water volume x desired return rate = gph of the pump.
Most run at 4 to 8 x it seems. Mine (55g) right now is just about 10x and its pretty fast so i wouldnt do it without a variable return pump personally.
I would maybe make sure the overflow is slightly overrated.

I ordered this havent installed it yet.

I have a Jebao DC6000 I was planning on using. Head height is ~3ft so at max power I should be able to crank 1000gph out of it. Total system volume is ~27g with sump so looking at over 30x turnover if I can hit 1000gph.

Unless someone has a recommendation for a powerhead/wavemaker that won't shred up anemones that is not an MP10.

30x turnover

I think that will blow water out of the tank. I could be wrong.

I have also used plastic canvas over my p heads. sponges work I hear.

I have the tunze nanostream 6015 and its shielded well.infact by btas sit right by ot lol
