I used spray cleaner for several years. I tried the Power Soak filter after another pool guy recommended it. I LOVE this stuff! It does a way better job. I keep 2 filters in rotation. I could generally get only 2 cycles on my filters before they'd look discolored and wouldnt keep the water looking good. With Power Soak, I can get 3 maybe 4 cleanings before I have to trash 'em. Power Soak is less expensive, does a better/deeper cleaning of the media, and I feel like the chemical is not as harsh on my skin. Try it! You'll like it!!
