Proposed Closed Loop System, your comments pls

[CurvBall]

Hi everybody,

Well, I'm starting to get ready to set-up my new tank after finally finding a new home

My tank is going to be 1m x 450mm x 600mm (deep). I'll be installing a centre overflow box.

I want to run a closed loop system (CLS) on my new tank and seeing as it is still in pieces I wanted to get your opinions on my CLS layout.
Please refer to the attached picture. Red circles indicate sump return. Lilac circles indicate CLS outlet while the blue circles are the CLS inputs. (The two big red circles are my drains to the sump)



I will be running two SCWD units on this tank, one on each CLS. Sump return will be a constant stream.

My return from the sump will probably rated in the region of 2000 - 3000 lph. But after head pressure, I'm looking at about 1500-2000lph.

For my closed loop, there is actually two of them, they'll be on pumps doing roughly 2500lph.

In total I guess I'm aiming for a complete turnover amount of roughly 7000lph
With my system only holding roughly 320litres, that gives me a turnover rate of 21 times per hour.


Due to the amount of flow in this tank, I'm going to be going with a bare bottom style tank with a thin layer of substrate for aesthetic purposes.

Please let me know what you all think. Any suggestions, advice, opinions welcome.

Thanks

I would like to see more elaboration on the outputs/inputs like depths of each? spraybars? just elbows? locline? Are these 2 different CSL's? are they gonna each have different pumps? Also im a little confused on the o-flow box, you have your sump returns coming up through the o-flow box correct? Would you drill the side of the o-flow box or just plumb up and over? There is alot to leave for imagination on this diagram but it does have a good layout for the most part.

For a clean look.It would be better to have the return line come back up into your overflow box. On the same lines I would have both the intake for the C.L. and the outtake(back to the tank) in the lower half of the back panel.This way you can hide them with your L.R.You can add PVC to the B.H. inside of the tank to direct the flow of the closed loop. This also can be hidden by the L.R.

If you decide to use SCWD units, they can be placed on the return from your circulation pump.
