Ok, I've learned some lessons, and this whole pool thing definitely reinforces the whole "the more I learn, the more I realize there is to learn, and the less I feel like I know" idea.
About 3 weeks ago I purchased a pool blanket. I cut it to shape, then cut it into pieces to make it easier to move, showed my family a system taking it off that will make it as easy as possible to put back on, and then I made my mistake. I didn't check the FC for about a week (it had been stable with my SWG for the past few weeks and I got lazy thinking I had it all set). Well, I went to remove the blanket and the pool was cloudy. I checked the FC and it was at 1. Sigh. I'm guessing that the blanket had some impurities and consumed some FC. That combined with the lowered light throughput allowed some algae that was already present to take off.
Anyhow, suck it up and SLAM the pool, that should clear it up right? It's been two weeks now, the water is back to the polished crystal clear look. The problem is that as I brush the pool each morning, there is a yellowish/greenish/brownish cloud that brushes up off the steps and the spa seat. It's not a lot, but I don't want to see it at all. I don't see it much, if at all, on the bottom or sides of the pool.
I just ran a complete battery of tests and came up with the following numbers: FC 23; CC <.5; pH >8; TA 85; CH 350; CYA 30; Salt 2900; Temp 74. Which yields CSI of .28. I have taken the step of adding acid to drop the pH and will test again in about an hour to see if I have pulled it back down enough. BTW, I'm not totally confident in the CYA test. I added enough about 2 months ago to bring it up to 65 (yes it was still a little low, but I was not confident in my reading then either). What consumes CYA? I know my kids splash a bit in the pool, but I really doubt they have splashed half of it out in two months...
Two weeks of brushing the pool every morning is getting old (I've learned my lesson this time - I think) and will watch the FC in the future. Now, I have not yet run the OCLT due to the fact that FC is remaining at 23 morning to morning with the SWG running at 80% 24x7 (before the bloom it was running at 30% for 10 hours) so I think it would fail. The CC has never risen through the whole process. Am I missing something or do I just need to give it more time?
