Overflow question. Please help

[cvrle1]

Hey all

I wanted to buy an overflow box for my skimmer so that I can get rid of all the scum on top of the water. I used paper and went over it, and it works in collecting it, but the problem is it just comes back after couple of days.

I went to J&L aquatics today but they don't carry them for my skimmer and they say that it does not exist for it. Skimmer I'm using is red sea prism. If it does not really exist for sale, I want to make one, but again no clue where to start from.

Please help me out.

Thanks

PS: if someone wants to make me one, I'll gladly pay for it as well, as losng as it's nothing tooooo expensive.
