New sump with overflows on top of dursos.

[Richie]

Hi,
I would like to find some info out on sumps, I have a drilled acrylic tank and want to put an overflow bow on top of a home made durso pipe.
This should work and hopefully will stop the whole tank draining onto the floor, also do durso pipes need to be reduced at the bottom? Or does it all depend on flow rates? Will over flow boxes work or will I have to section of the tank?

Thanks for any help.

If the over flow is set up right it will only drain the amount of water that is pumped into the display. If you keep the pipes up high close to the water level it reduces the splash niose. As far as reducing it at the bottom I have no idea.

also do durso pipes need to be reduced at the bottom?

Im not possitive that you have to reduce them,but I did (per the sites instructions).

It depends on the size of your bulkhead hole. Example: For a 1" bulkhead size, Durso says a 1.25" standpipe works best. So, in that case it would be reduced. Bulkheads 1.5" or larger can use the same size standpipe as the bulkhead. I run 1.5" standpipes with 1.5" bulkheads. Works fine.

Thanks for all the replys guys.

Mine are 1.5 bulkheads with 1.5 standpipes, I was going to reduce it but as you have good results then I will go with that.

Do you think that acrylic boxes will work well as overflows on top of the dursos instead of closing off a section of aquarium?

Thanks

Yeah, it should work. Here's an old picture of one of my tanks with dual 1.5" overflows. My overflow boxes are made of glass, with acrylic covers to hide the overflow boxes and standpipes, but you get the idea. The elbows you see to the inside of the boxes are 1" returns.

Thanks very much for the help.
