Newbie here, Looking for advise on UV water cleaner for a saltwater pool. I have never had a problem with algae or anything else until we got a Lab puppy that absolutely will not stay out of the pool. Just thinking this UV thing might give an extra layer of protection. Comments anyone ? I have read both positive and negative.
Thanks in advance.

Saltwater , 20,000 gallons, Atlanta Ga. , pebbletec, some afternoon shade from trees. ???? don't know what else to add here.
