I posted this in another thread, but no answers. I will try again

OK so i have an existing 20 Long pretty much stocked. It has a HOB CPR skimmer and HOB CPR Fuge...also 2 MJ600's runnin for flow. I am getting tired of all the ugly pumps.

SO my question:
I want to get a sheet of black acrylic and make an in tank overflow for the HOB skimmer and fuge...i dont want to drill or anything as i already have the HOB stuff. I would then use the two MJ's and Loc-line to pull water out from behind the fuge. I know it wouldnt be terribly efficient and some clean water will be recycled back into the skimmer, but my tank is only a 20 L and i think the skimmer can handle a little inefficiency. My main fear is matching the inflow from the overflow teeth to the outflow of 4 pumps (skimmer (MJ1200), fuge (rio 400) and the 2 MJ 600 for return). what do you guys think??

i will take any and all advice!!

no love?? help please? I want to try to do it this weekend

the flow from the teeth will match the flow of any pump, water can only go in as fast as it is pumped out

Jasutton, I am planning on the same mod with both my 33 salt and 55 fresh. Have XP2 attached to both and just wanted a small over flow to keep the surface clear.
And as Mr. Pink Floyd said the teeth with allow as much water to flow throught as is pumped in. :thumbsup:
The thing to watch is if the over flow is to small it will empty to quickly with your evaporation. I am going to have to watch very closly of have an auto top off to keep things safe.

thats what i was thinking...

but i am also worried that with basically 4 pumps taking water out of the overflow, it wont have timeto flow in...make sense? I am just going to have to fiddle with it i think

To account for the evaporation problem & increase flow you might put some other holes in the overflow. The RR tank I just got from Oceanic has a line of holes about every 1/3 of the height (7" & 14" in my 21" deep tank).

They're not very big, so not much flow but it might keep things moving.
