Another question on a 135gal

[redstang]

The one I'm looking at has one hole drilled in each back corner. What could/should I use those for if I build a c2c overflow for a bean type drain system? If I used them for returns I'd have to camoflage the return pipes. If I can drill the bottom glass I could dump the c2c overflow idea but still use the bean drain.

Looking for ideas here basically.

Thanks!

Hmmm... closed loop? Drill one drain on the back panel, put a screen on it and voila?

Was thinking about closed loop too butdon't know much about them as far as pro's and con's. Would CL preclude the need for PH's or would it just be in addition to? I was planning on picking up some MP40's.

Build an overflow box and use them as drains.

 

[crewdawg1981]

The closed loop could be used in addition too or part of the flow. are the holes at the top of the tank or on the bottom at the corners?

 

[redstang]

They're on the bottom in the corners. I could always plug them with bulkheads.

I'm thinking rather than drilling anymore holes for the CL I can just put in a a 2-3" stand pipe, put a grate over it, use rock to mask it, and then run the return to the other drilled hole and distribute it from there. Was also thinking that it might be a great way to incorporate a UV sterilizer or something in the future. Just have to plumb it up right. I don't want to spend too much on it as I'm pretty set on getting a couple MP40's. And the glass is only .5" so I can use my MP10 in the back.

So stoked about this tank.

I think the problem with this idea is that it will be hard to syncronize the return pump and your drain valve. Having the standpipe only 2-3" tall with no overflow will create a syphon which will drain water very fast: probably much faster than your return pump. You could put a gate valve on the drain pipe to combat this issue. However, then you will need to make sure that you are draining as much water as you are returning to the tank. I've never tried this, but I would think that it's hard to achieve. Finding balance that is close is probably do-able, but to match them exactly, I fear would be very very difficult. One of the advantages of having an overflow is the avoidance of this problem.

If you do not want to put an overflow in your tank, i would suggest extending the standpipes almost to the waterline. maybe you could drill holes around the top or something. You could still mask the pipes with rock, or whatever.

JMHO. good luck!

I can't wait to see the build thread on it, Jason!

Go cl and have more flow vs unsightly powerheads

Sorry I wasn't clear. The short stand pipe would have been feeding a closed loop so there shouldn't be any drain or siphon issue to deal with. I plan on doing a bean type overflow and will drill a few holes along the top back to accomplish that.
