This is our first year as AG pool owners...so far so good...our water has looked pretty clear for the most part except at night it looks a little cloudy right in front of the light. You can see teeny tiny little "partlicles" floating around. I added clarifier yesterday per the pool store's advice & we vacuumed (can't really tell any difference)...We have a SWG but I went ahead & added 1lb of cal hypo shock this evening since we've had alot of dirt/pollen/leaves in the pool & alot of swimmers. My question is...does the water normally look like this @ night with the light on? And if not could it be due to the dirt & pollen?? Thanks!!
