Just one more question for this week. I removed my water tank from the boat so that I could clean and paint under it. The tank sits on a wooden supports. When I inspected the tank I found it badly corroded and full of holes on the bottom. The tank is made from aluminum and has a ground wire attached to it. Any ideas as to why it would be full of holes. I'm planning on having one made out of stainless steel. Will that also corrode.

Aluminum tank - normal chlorine in your water corroded the tank. You also probably found a lot of 'white sand' (aluminum chloridte) in the bottom. Aluminum makes LOUSEY water tanks because of the attack by chlorine.
Stainless steel tanks should have a minimum of welds, the welds ground smooth, .... then the tank should be passivated. Stainless 316 is the material of choice for water tanks. Polished stainless (internals) is best.
