This may be a silly question, but sometimes after my pool has had a very high bather load (lots of kids and adults for 6+ hours), the water will become kind of cloudy. When testing the water, I'll get at most .5 CC, which will be gone by the next day. Usually, I'll raise FC to about 7-8 before a big swim party, and then about 10+ after it's over. The cloudiness isn't too bad, I can still see the main drain cover, but it will take about 3 days to get back to crystal clear running the pump overnight after the party, then about 6 hours a day thereafter. I've added some DE to the sand filter, and it makes the thing clog up quick and I'll need to backwash in a day or so. We had a bunch of kids in the pool last night, and here's the numbers from this morning (still cloudy):
Last night I added bleach to get FC to 6, it was 4 after everyone was out of the pool. Does this cloudiness happen to anyone else? Is there a better way to stop this from happening, or do I just deal with it? It sometimes is embarrassing, because I always get compliments on how sparkly my water is.
