Have you been thinking of converting to a salt water pool?  We converted an older vinyl lined pool to  salt system earlier this week.  This client had chronic problems keeping the water algae free due to older equipment, broken laterals in the sand filter etc.  By converting to a salt system they can simply super chlorinate when they need a boost of chlorine and not worry so much when they go away for a weekend.

Here is the before and after pictures:
