i just bought a used Elite Spa that appears to be in good condition. There doesn't appear to be any mold growing and I tested all the jets/heater ex before moving it. It looks pretty clean. The spa movers did a great job and I am am filling it up for the first time since it had water in it yesterday. Should I still use Ahh-some even though I don't see any mold or feel any slime? I am going to be using chlorine. Anything else I should do or replace right out of the gate?
