Raising the end of a flood and drain table

[jahman]

Hi,
What is a good way to keep proper drainage on a table? Raise it a 1/4" on the far end and have 2x4s underneath so it does not sag?

I am getting a TON of gnats and I think that's what its from..poor drainage.

Thanks in advance.

what size is your tray? i am asumming 4x8 cuz the 2x4's in the middle a golden rule is 1/4 inch per foot....to get the standing tray water out back into the rez. also if there some gnats check your ez. might be worms in it?.. if so medical grade hydrogen peroxide.... hope its helps you bro...

It is a 4x8' table. I need to get the drainage going better. I'm not sure what you meant by worms? I'm sure they are gnats and they come back every time.
