Jim what kind of material is the screen you used for the bottom 6 inches of the divider between oyster shell and pump area? I was told not to use metal and am afraid regular old fiber glass screen is to fragile and would clog up to easy. Any thoughts would be great.

I saw an ad on craig's list for 4x8 fiberglass sloughing boxes. North Carolina I think.

As far as pressure treated lumber. It won't kill the crabs but the chemicals are ingested into humans. The chemicals in the wood will bleed into the water then into the crabs.

Ended up using Exterior grade not PT and 2 coats of Gluvit.

Thanks for the info. I ended up going with the Magnatec 1800GPH. Tank has been functional for almost 2 months now and currently has 26 crabs in it, all seems good right now.
