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

looks pretty good really, the onlt thing i would ghange is. i would put the cls inputs higher and the csl outputs two lower and two up higher for a better flow through out the tank other wise i think it looks good good luck aqnd lets wait on some other opinions.

[CurvBall]

Thanks for the response wooddood.

Here is an updated drawing of the system. I do agree with what you said and have made the changes on my diagram below:



Should I put 'Y' adaptors on the end of all my outputs? Was thinking of doing this with the sump return outlets, but the more I think about it, maybe it would be wise to do this to the CLS outputs too?

[wooddood]

i think the y's are an excellent idea. and the new design looks great i think you have it covered really well now. keep us posted with pics as you progress looks awesome.

[CurvBall]

Thanks again wooddood.

I guess I'll go home this evening and mark out where the holes will need to be drilled. Should be able to get it all drilled and set-up by the end of April, perhaps sooner The budget is just a little tight after moving etc.

Perhaps some others with CLS on their systems will comment on my design, just want to make sure I'm doing the right thing.

Thanks again.

[wooddood]

yeah lets wait and see what some of the others have to say first, better to be safe then sorry before the holes are drilled lol.

I wish I knew enough on this matter to post an opinion that was worth something, but it looks like it ought to work..

Tagging along to see what others will say.

heres a bump for ya

[CurvBall]

Hey all,

I get some interesting advice from other forums.

I was told to make my CLS inlets bigger than my outlets, it will help with lessen the 'suction' ? At the moment that is why I went with two inlets per loop. I'll post another diagram later today, when I find time at work.

I guess this is just a glorified thread bump :>

[wooddood]

yeah post another diagram, i would like to seeit .thanks.

[Icebox]

I Think a second reaso to have more outlets feeding the pump would be that there would be less "pull" on each one. This would help keep critters from becoming stuck on one of the bulkheads while climbing around...

I have not figured out exactly what I want to do with my tank, but You ought to check out the www.oceansmotions.com They appear to look great at changing the waterflow patterns.

Just a thought.

[CurvBall]

Hey everybody,

Here is what I'm feeling will be my final plan to work from for my CLS.




Let me know what you think.

Thanks.

[Montanareefer]

Looks like a bunch of holes!

I think ya got a plan!

[coral keeper]

i'm lost can you explain that diagram?

[wooddood]

you should have plenty of water movement. just a suggestion i would put ball valves on all the inputs because you may have to throttle that baby back some. also i would pm mike [mojo] and have him take a look at it before you start drilling any holes, he's sharp on water movement and everything else for that matter lol.
