Or along this line of thinking. Lower the overflow teeth/slots by a half inch with a dremel. Just keep in mind that if you ever fill the aquarium to the top again you would need extra room in your sump. I believe for your tank a half inch would calculate out to around a 4.5 gallon increase in the sump.frnchjeep;4970973;4970973 said:

To clarify, the issue is not so much the poly's hitting the flat part of the brace.
It is when they come up and hit the edge of hit, like them hitting a wall.
I lost and endi to this. He was a somewhat skittish poly, just crushed the edge, died few days later.
Thus the strong feelings on this.

I'm using a HOB overflow. But the idea is the same if I cut the lip of the intake a little lower that should do the trick.
