A few days ago I upgraded the filtration on my intex 15'x36" easy set pool to a sandpro 50. The sandpro is rated for pools up to 5x's the water volume that I have. Prior to the upgrade I could not keep the water clean, but now it's crystal clear. The question I have is should I continue to run the filter 24/7 or should I buy a timer and have it run off and in throughout the day?
