home made skimmer

[paul]

 I have to replace my very tired skimmer and was thinking about making one myself. Its a larger shimmer ,almost 30" deep and about 24" square. A replacement for this will cost upwards of $700 so I if I could find a suitable  high density poly box I could probably fabricate one myself.
Any advice on construction or possible source for such a box,  would be appreciated.

 Thanks,

You might try Craigslist. I found both a skimmer and biofalls last year for $100 for both.
