how does this look.....

Zoo...what do you mean really makes a mess ????? Dont quite understand?

[ZOOT098]

when i did it i had a setup like hornet suggested
very similar to yours but with the ball valve for the drain below a wye connection and cut back, creating backflow to divert water to the fuge
problem was the raw water has suspended debris in it which settles on your rock and macroalgea thats in your fuge, creating a mess

i actually took my fuge out for the time being

you may be better off to run a small pump (35-40gph) from your return section, with a small piece of 1/2" tubing into your fuge then just let the water overflow back into the return section

you will be putting just as much water back into the return section as you are pumping out so it shouldnt be a problem and the water you are pumping into the fuge will have been skimmed first

heres what i mean, excuse my crude artwork

THANKS ZOO, i SEE WHAT YOU MEAN. I THOUGHT I READ SOMEWHERE THAT YOU SHOULDN'T SKIM THE WATER GOING TO THE FUGE ?? THANKS FOR YOU INFORMATION!

[daugherty]

you want as much raw water as you can get but the skimmer will not get it all before the water get to the fuge.

the red is the return to the tank and the blue is the drain from the tank my skimmer is in the drain and the middle is the fuge

The ball valve on the return line is good practice. How will he replace the pump when it fails? The ball valve will prevent the tank from draining all over the floor in the event he disconnects it to replace/repair/clean the pump.

Is this how most peoples tank are set up? I just have anti siphon holes. :shrug:

Thats all I got.Nothing mechanical to fail.Plus I keep the return nozzles just about 1/4" under the water surface,just in case.

cgoodman...the ball valve on the return line is to regulate the flow back to the display tank, mainly so you can restrict the flow if you are pumping more back to DT than you are draining

Thats what I said originally. I was just curious about what RC had said. I dont know why anyone would only have a ball valve and have a chance of creating that reverse siphon.

[ZOOT098]

i must have misread it
some people have a hole drilled in their return line above the water level
it breaks the siphon if electric fails

of course you right, for the 3.00 that a check valve costs, why not have one

OK....here is the beginning stages of the sump build

I finished the skimmer section and will let it dry then put the last divider in for the fuge section.



I will still build it with the middle section being the return but I will plumb the skimmer to put water from the skimmer section to the fuge section.
