Sorry i am finding it hard to understand what you mean by the overflow from the link. Is the overflow pipe the intake pipe for my sump?
Do you mean it piggy backs of the out take pipe for my canister fliter and goes into the sump?
it is the the overflow, so it takes the place of drilling. so it takes water to the sump.
it uses the principal of siphoning to get water over the glass wall, the water level in the tank wont fall below the top of the green pipe
