The chlorine will dissipate quicker in warm water temps than cold, but you also may be fighting something in your pool that is causing the fast chlorine consumption. Just because you have 0 cc doesn't mean you don't have an algae bloom starting. And with a CYA of 60, a Cl of 2 ppm isn't enough to kee the algae at bay. If it were my pool, I'd shock it just in case...
