Hi,
All summer, I've been fighting some algae, with a few good runs, and have noticed a few things:
- TA is always going down. For example, it can drop from 100 to 80 in less than two weeks. Added way more baking soda then usual this summer.
- PH is always pretty high. Added way more acid this year, perhaps 16L this summer so far.
- Added at least as much liquid chlorine as previous years (at least 120 liters @ 12%)
- My CYA is low purposefully, under 30, since I wanted to try that approach this year and see if chlorine would be more potent
- Shocking my pool to 10+ FC. Doesn't go down drastically overnight, but not measuring any CC. Is that normal? My CC reagent is at least 3 years old however.
- Even when shocked, algae (green color) keeps showing up in same spots (mid-wall on deep end, one corner) after brushing the day before.
Feels like I'm in a chemicals rat race. Should I be always be adding so much baking soda? Is adding so much acid normal? Do I have some special algae that is very hard to kill yet doesn't show up in CC?
