I have the same size tank. I used to have 2-175w MH on mine at first but upgraded to 2-250's instead. I'd say go with 250's instead, If you already have th 175's they should be fine for clams just keep them up a little.

Also what are the PC for attnic sup?

I agree with James. I went with dual 250's when I had my 75gal, but like already mentioned, the 175's will be just fine
