Hello all. I am writing to explain what I've gone through in the last few weeks and to check my actions against your recommendations. I use the Pool Math app so may latest readings (most of them anyway) should be found under my username. But here's the story:
1) Old constant-speed 2hp pump went out again, so I elected to upgrade to the Jandy VSP model. This is coupled with my Hayward t-3 SWCG. This all happened at the end of spring.
2) Worked with my pool equipment provider to set a schedule of high-speed for 4 hours and then low-speed for 7 hours, which seemed to work well until it got hotter. Then I noticed that chlorine levels kept going down even though CYA was fine. We upped the high-speed to 6 hours and low speed for 5-hours. This seemed to help, more or less.
3) Then last week hurricane Debby roared through, and I ended up having to dump 7 inches of water out of the pool over three days. And it was HOT! And right before this I had guests who were using the pool way more than I normally do. So by late last week I noticed an obvious haziness to the water and I couldn't keep chlorine above 2ppm. Based on the advice here at TFP I reasoned that I had a mild algae outbreak so I just went through a 3-day SLAM and the water is clear, OCLT was within bounds and no CC. So hopefully I'm out of the woods.
So now my questions:
1) I will wait for FC to drift down before starting up the SWCG and balancing the pH, as recommended. But once I get that going again, I've seen some advice here on running the VSP 24x7 instead of the schedule I've described. Is that the general recommendation?
2) Also, I saw one post that said the SWCG should be rated for 2x the pool size. My pool is 13,500 so the t-3 is pretty close to its maximum capacity of 15,000 gallons. Should I consider moving to a larger size when it comes time to do this?
3) Based on what I've described and my questions, what have I overlooked, or what should I consider doing differently? Is the scenario I described a plausible reason for this to have occurred, or am I overlooking something else?
TFP has always been a big help so I look forward to any advice you can provide. Cheers!
