I'm going BB (question)

[Saltysteve]

I have decided to go bare bottom, the amount of debris that I keep clouding my tank with my Turkey Baster is just too much. I am in a really good position right now to do it so that makes it a lot easier! I am moving
I do have 2 or 3 rocks with a fair amount of hair algae; what is the best way to rid them of it?
Cook/boil/bake
fresh water dip and stiff brush
salt water and stiff brush

Thanks in advance!
Also, if anyone knows where to get a larger piece of the "cutting board" material, can you tell me? Wal-Mart wants 7 bucks for a 12x18 piece
