Our salt system is failing us. When I do a search for info on Pure and Clear, seems like it is around no longer. We have had ours a few years. Our pool is turning green. We are presently shocking it and using algaecide trying to clear the water (above ground). What is the life time of one of these systems? Is it just time to buy another one? (probably have had for 6 years). Also, if we decide to go the chlorine route and discontinue salt system....what will this require? Emptying the pool to rid the salt? Need some advice.....anyone use a salt system?
