Followed BBB Method all summer and pool looked great. Used it Labor Day but then weather turned cool and we figured we'd be closing pool. I kind of forgot about pool for about 1 week and when I went to check on it, it was green.
I can't see the bottom..I can only see the first 2 steps into the pool. Checked FC and of course was at 0..stupid me. Went to SLAM it this past Thursday. According to pool math with CYA level of 40 should SLAM at 16.
Starting pH pre green was steady between 7.2-7.5 for weeks. Got FC level up to 16 and turned filter on 24/7. By Saturday didn't look any better. BUmped filter as the pressure was getting a bit high. Still no better by SUnday so yesterday afternoon drained the filter and replaced the DE. FC still kept at 16+ (I added a little extra bleach and had it at 20 for a while). CC is never greater that 0.5. This morning still looked just as bad.
One other thing to note, for some reason we didn't get a closing valve between the return and our filter so when we go to drain the filter, eventually it just drains directly from the return too. Need to add one on, but in the meantime I wanted to check the water coming out of the filter to make sure it was clear and the filter is actually working.
What else can I do???
