I have scrubbed everything in the pool, vacuumed and brushed and I see no visible signs of algae however when I was scrubbing the solar blanket I found algae and it won't scrub off so no more blanket. That may have been my culprit last night. I added bleach and right now I'm sitting at 21.5 FC and .5 CC. guess we'll see where that goes over night. I can't test anymore today I have mares about to foal so I need to be at the barn. Hopefully I've got this pool thing on the run and in the morning it won't have dropped to much. Thanks to all who have encouraged me and helped. Most appreciated.
