pressure treated lumber to build a stand and canopy??

[agoutihead]

you know the wood they use to build decks, is that better to use than regular wood?
i was thinking of using 4x4's for the outer corners... is this overkill?
im doing a 75 gallon

Its treated with Copper-Alkoid-Quat. very nasty stuff when around moisture. I would avoid it
Overkill is fine if it gives you peice of mind. 8lbs per gallon of water is nothing to sneeze at, but yes 2x4 will work fine.

hmm. thats an interesting tid bit of info about the copper-alkaloids. i guess ill just avoid the treated and paint it down with killz/some type of sealer
