Pool Math vs SWG Recommendations

That’s great, you guys think of everything! Yes, I did, thanks! I put in 25 KG, but more is recommended. Fortunately,I do believe there has been a reduction in sediment collecting on the tiles and bottom. I will know better when I vacuum again. However, I am still struggling with high pH, which I think might have something to do with the 4m drop from the pool to the gutter. From my understanding, water features like this aerate the water, causing the pH to rise. Is there anything else I can do other than adding HCl every other day or so?
