Proposed Closed Loop system, comments pls

[mojoreef]

You could put the inputs for the closed loop in the oveflow you just have to worry about a couple of things. One is that you would have to make sure that no bubbles near it, perhaps a standpipe will keep the water spilling over the overflow to just the very top and then draw water from the lower reaches (tight plumbing though)
The second thing to watch for would be, would the overflow box be able to draw into itself enough water to accomidate all the pumps that are going to be drawing from it. I would do an experiment prior to drilling.

Hey Curvball! Looks like your going to have an awesome set-up when you get it all figured out. Mojoreef(Mike) also did my closed loop design for my 60 gallon cube tank and like has been stated having two inlets from the closed loop down toward the bottom is very important for keeping detritus off the bottom of your tank especially for BB like I will be doing. Here is a pic of the closed loop design Mike did for my tank.

Morning everybody, is it morning? Hope everybody had a good weekend. I managed to play some more with my new tank and looked at various ways to fit my CLS system into my tank.

Just want to thanks to mojo and everybody else for their input regarding my design.

Mojoreef said: "One is that you would have to make sure that no bubbles near it, perhaps a standpipe will keep the water spilling over the overflow to just the very top and then draw water from the lower reaches (tight plumbing though)"

I have ball valves on my outlets to the sump and I use them to control the water level in my overflow chamber, but would I still need a standpipe then? As for tight plumbing, I'll do all the plumbing 1st and then build the overflow box around my drains etc.

Curvball,
Be careful, there are copy cats lurking in the shadows.

Thanks for your concern Ed Hahn. I'm not too concerned who copies my idea because I know I'm not the first one to try a CLS.

I will post an updated diagram of my CLS system later today, I welcome addition please.

Thanks again to everybody for their help.

Curveball,
I was just saying I liked it. I am looking at more circulation in my tank also. I have been dreaming of this. Thanks! I was thinking of running a few 3/4 inch Sea Swirls on the surface and using a spray bar on the bottom about 3 inches from bottom with 1 inch bar. I was also planning on running a Sequence Stingray pump 3800 gph. How do you think that will do in a closed loop on a 90 gallon AGA?

Updated CLS

Hey guys,

What do you think now?

Glad you like my idea Ed

I'm sure the other reefers can help you out, I'm in the same boat as you, clueless

Final circulation layout

After much thought and discussion with many aquarists, I've decided on my final layout for my new tanks circulation.

I'm going to go with a bigger return pump split into two return lines each with two outputs. One will be a constant stream while the other line will run through a SCWD unit. The constant return lines will be located in the top of each corner.

My closed loop system will now only run one pump with a SCWD unit with each return being split into two.

here is the diagram:

Please can i get your comments etc.

Thanks.

I think it looks great! I'm excited to see how it works for you!!

 

[CurvBall]

Thanks Nikki.

I'm busy speaking a friend of mine who runs a marine aquarium company (Duraquatics) here in South Africa to put my tank together.

I'm getting all my equipment from him as payment for his website I'm currently building :> And for site maintenance, I'm getting paid in livestock.. schweet deal or what!

My personal site for my tank is starting to stir, so if you're interested check it out at: regalprojects.co.za

More problems... solutions.

Well as my luck would have it, I've run into more problems with my new tank.

I'm going to basically get the sucka built from scratch, which in itself isn't a bad thing, just going to cost me more cash.

Going the best route as for as doing this as economical as possible ( I have 4/5 of a tank at the moment, no front glass yet) this is what I've come up with. I'm going to install my closed loop intakes in the 'new' external overflow box. This will also allow me to attach prefilter to the intakes because this CLS is going through a SCWD. The water level will be controlled inside the overflow box via stand pipes and valves as suggested by Mojoreef.

The drawing is to scale.

What do you think?

 

[mojoreef]

The plan looks good but again itas all a matter if the overflow box can get enough water into itself to handle the return pump and the CL pump at the same time. running the overflow boax on the outside means that you are going to have to cut a wier into the back of the tank for the water to come from the tank to it, so how big is the wier going to be?? that will tell us if it can handle both pumps, can you list the total GPH on the two pumps being used???

Hi Mike,

The proposed wier will have a length of 300mm.

The drain to the sump will be a single 32mm pipe.
The CLS drain will be a single 32mm pipe.

Here is an updated drawing with measurements (sorry but everything is in millimetres, we use the metric system here in South Africa )

CLS pump is rated at roughly 3000litres per hour.
Return pump is rated at 3500litres per hour but after head I reckon it will only be pushing 2000litres per hour.

[mojoreef]

Sorry buddy its been a tough week at work. Lets do some math.

ok your CL input will handle about 1600gph so no problem thier.
and your pump is pushing only 800gph

your return pump is pushing around 500gph and the input will handle that no problem to.

so the total water coming into the overflow box will be 1300 and that size of box should handle that no problem to. So it all looks good on its ability to handle things. your total flow in this tank which I believe works out to about a 60 gallon is going to be around 1300, the closed loop may be a little small to get the right kind of flow in the tank, but I would just hook it up and you will be able to tell from thier. if you need more you can just upgrade the cl pump to one that is a little stronger.

Hi Mike,

Thanks so much for your valuable input it was worth the wait. Your knowledge is really appreciated... look out for credits on my website soon.

I probably will upgrade my closed loop pump in the future, thanks for the tip, but I got this pump lying around already.

Perfect, I'm going to order my tank tomorrow!!

Thanks again so much for your help, I owe you a beer.

Rock n Roll.

glad I could help, make sure we get lots of pictures.
