now that i fully think about it, restricting the 2nd overflow wouldn't work. i may have to get both overflows to join with a pvc pipe which has two lines off it. 1 to the fuge and 1 to the skimmer section. the fuge line will have a valve to slow down flow thru that section.
i think modifying the fuge a little would help too. instead of having bubble traps, just have a single piece of glass that keeps the water level high and plumb a piece of pvc with an elbow thru the wall and into the return pump section...
that way there is heaps of room should the return pump stop working.
so many choices... :lol:
