Overflow ?

[cartman101]

When I set up the overflow and let it run will it sink the main tanks water level a couple of inches? If so i'm screwed cause I just drilled the hole in the pvc when the overflow wasn't in the tank and working. Little nervous here.

It will drop the water level some... to the top of the slots of the overflow.

 

[my way]

Raise the box. Some are adjustable, if not put some shims between the tank frame and the box. The anti-syphon hole does'nt have to be under the water line, but having it that way will reduce saltcreep from the splashing as it squirts out, it will also be quieter if it's under water.

and if u get the slurping noise, just put one bioball where the tube starts inside of the back overflow box that leads down to the sump.. doesnt restrict waterflow and cuts the vortex or whirlpool effect that causes the slurping noise! my sump is quieter then a canister filter!

Please anyone? I want this thing set up today. The lfs said the raise one drain so that it would be a back up and then add a ball valve at the end of the main hose thats working.
