The TA is a little low, but Higher TA will drive the pH up faster. And the lower the pH, the faster it wants to rise. There is really no reason to try to keep the pH at 7.6 and there is nothing wrong with letting the pH sit at 8 or so.
I had to log in just to see how your drainage was holding up :)
Buddy lives down by you and said Sahuarita was passable. I imagine he went over to Old Nogales and north.
You should not need a check valve between the heater and SWG. If you are going to add solar, then I would put the flo vis right after the filter which is where you will need one for the solar. That is where I put mine.
The sight glass on my filter is removable so I can clean it. It only sees water when backwashing, so the stale water sitting in it will allow algae to grow.
Not sure if the Intex is similar, if so, just remove it and clean it out.
The slope from the pool to the drain would not need to change to maintain the same drainage. They would just need to raise the drain up a few inches further from the house. But the other impact is how that would then interface with whatever patio is going to be part of the covered area. So the...
You can't remove the system completely without destroying the pool.
Do you have a separate set of wall returns that are not part of the Caretaker system? I always recommend having this loop for reasons just like this. If you do not, then you do not have much choice but to get the caretaker...
I would go with a SWG on the spa as well. I assume it is sitting out and exposed to the sun just like the pool?
Perhaps look at some of the smaller SWGs for AG pools? You can go large on the cell and just run at a very low output.
I agree with the others. Would suggest a deep cleaning of the tub and then stick with the Dichlor / Bleach method and avoid the Bromine from the start. You can't just switch from bromine to chlorine without a full water replacement...
You can use them next spring, but they will have lost some of their strength. So, be sure to test after adding to be sure you hit your targets.
Just keep them in the dark cool garage.
There is no recommended strength for the bleach. Use whatever gives you best $ / oz of chlorine. I suggest you start using the app and in it there is a calculator to allow comparison shopping of different strengths.
Just be sure there are no additives in it if you use household bleach.
The...
:wave: Welcome to TFP!!!
First, high phosphates are not the cause of your algae, low chlorine is the problem relative to your CYA. See
1. Algaecides are more for prevention of algae (although not needed at all if you maintain proper chlorine levels) and will not do much to get rid of algae...
