First thing's first: are you following TFPC or are you following Pooli? Are you using their products and how are you testing your water? Your logs show a 40 ppm CYA increase and a 100 ppm CH decrease over a single day, that sounds like something you'd see from test strips... You can't mix...

Your comment makes no sense. One of three criteria is that your pool is free of algae, so how can you pass the and still have algae? What did you actually do?

Still wondering what this "24 hour algae kill" is...

What is that? Why?!?

That is a DPD test. It's a color matching chlorine/bromine test that's a step up from the yellow OTO test, but not nearly as reliable or precise as the FAS-DPD test.

If your CYA is 30 then your SLAM level is 12 ppm FC.

What is the current salt level of your water?

The simple answer is "no". Floc has to be swept and discharged from the pool by vacuuming to waste, any left in the water can ruin the filter.

I have no experience with AquaClarity, but @Ahhsomeguy could probably answer any questions. As for the tub itself, IMO the water probably just needed changed and it's a coincidence that the CYA is lower at the same time the water is fresh.

Hmm, what process pushes water through the laterals up through the sand... :unsure:

Hi. I'd just like to confirm that we're on the same page regarding this algae. Could you describe it and what traits it has that indicates it is mustard algae aside of it appearing when the FC is high. Please don't take this request as an insult to your efforts, but you've done a lot that...

Most, if not all cells are like microwaves: when you set a % it just cycles on and off. So even if you set it to 50% it's still running at 100% for half the time and off the other half of the time. It shouldn't be an issue to run it this way.

What you are describing is just a backwash, but instead of using the high flow of a pool pump you'd be using the low flow of a garden hose. It would not replicate a deep clean, it in fact would be less effective than a normal backwash.

Well, I cannot say for certain without more information, but the use of highly acidic trichlor does not typically bode well for the longevity of heat exchangers. If you're putting them in the skimmer, then that's definitely the problem. If you have a feeder but no check valve between it and...

How are you chlorinating the pool?
