We had a heat wave in New England. 4 days of 90 degrees or more then we got some heavy rain and it cooled off. That's when my pool got cloudy (not green but can't see deep end bottom). My pool had heavy use during the heat wave. 18 people on two straight days and five in the water on the third. The FC was maintained at 2.4 or more throughout by my SWG. We are also in the midst of yellow pine pollen season.
Last night when I noticed it starting to cloud up the FC was 1.5. I only had 1.5 gallons of bleach on hand so I poured it all in and ran the filter all night with SWG on 100%. Woke up this morning and the situation has worsened a bit (more cloudy). Heading out to get bleach now to shock. Also going to clean my filter and put new DE in (pressure is a little higher than usual. Here are the reading (TF-100) from this morning.
Is this the start of an algae bloom?
