Hi there! I'm back! Thought I'd report after a few months. If you recall, my original problem was my pool's acid appetite to get pH down. What appears to have worked is to get my TA down to 70 and have not used acid since then as my pH stayed at 7.8 or below. I've used liquid chlorine...

Yes, I should get one. Per poolmath, CSI sensitivity to salt is nothing compared to pH, though. I also can’t taste any salt. If I remember correctly, salt starts to taste at 3000 ppm.

CSI is .14 per poolmath. Don’t have a salt tester, though, so I assume 1000. I don’t have SWG and I don’t use borates.

Guys, I think we got this. Compare to my last post on 9/12 above. I have not added MA since 9/8. All I have been doing was bleach. PH never got above 7.8. TA has climbed a bit since 9/8, but I think the key was getting it down to 60 in the first place. It appears MA dosing will be now be...

Could this be?! Last time I reported data was on 9/8, when my pH was 7.6. Below are my test results 4 days later and my pH is still 7.6. Maybe the TA of 60 did the trick. I did not dose any MA during this period. We need to note it has been raining, the sun hardly appeared, and temps have...

I think I’ll eventually get TA lower than 60. When My pH goes up I have not noticed as rapid a rise in TA, if any, so far. So, repeated doses of MA bring both my pH and TA down, but TA appears not to go up when pH goes up. Then I have to do MA again. I’ll let TA get to 50 and if it still does...

Seems like the only effective way to keep pH down is to use pucks, at least for me. However, keeping pH down with MA is easier than fighting CYA.

I did. Thanks.

Makes sense. Thanks. I thought x ppm TA will be lowered by x amount of MA regardless of pH level.

OK, thanks. But why from 8 to 7.6 instead of from 7.8 to 7.4? To allow for the effects of rain to dissipate?

I give up. Despite TA being lowered to 60, pH rose from 7.2 to 7.6 in 3 days. TA has remained at 60 for the same period. Now we need to note that the pool has filled to the brim with rainwater the past 2 days. I think rainwater is usually acidic but pH still rose despite that. Because of...

I adjust the FC for that. I try to keep at around 7-10 with bleach, never lower than 5. I had not needed to shock with this. No algae. It used to be about 100 early this year.

CSI is -.5, according to poolmath. Should improve as pH goes up, which I think it will. Of the recommended levels, TA at 60 and CYA at 60 are out of range.

Ok. I’m back to bleach. Waited for pH to reach 7.8 and got pH an TA as low as I dared. New starting point is as follows. My objective is to find a low-maintenance sweet spot where I do the least dosing of MA. If this fails I will wait for pH to get to 7.8, get it back down to 7.2 with MA...

I forgot about aeration increasing pH. I pointed the jets down. Was not an issue with acidic pucks, but could very well be with bleach.
