I bought a Pentair Sand Dollar filter a couple weeks ago, replacing my Hayward S200 that had a crack in the top of it. The water has been dirty/cloudy ever since I installed the new filter. Vacuuming picks up the dirt from the floor, but the water quickly starts to cloud up while vacuuming, almost as if I was vacuuming in recirculate mode rather than filter. I'm 100% sure I put in the right amount of sand, but I'm wondering if I didn't put the right sand in when I installed it. I used Quikrete pool filter sand from Lowes. Does it really matter what brand or kind of sand I use? 10k gallon IG, 3/4hp Super 2 Pump, no problems before I put the new filter in. I added some DE the way that pool school recommends and it really didn't help any. Any ideas?
