Hello,
I've been having some water quality issues lately (calcium hardness of 900!) and have a pool service so am taking more control myself. Been studying everything I can here and have the full TFT test kit and using it regularly. Because of the above-mentioned calcium issue I drained and re-filled this week. Just about done adding all the chemicals to get it well balanced for a fresh start and it looks great. So I reached out to my pool guy (this is a vacation home so we can't do it all ourselves as we can be gone for weeks at a time) to let him know what I did and to alert him to not add anything without testing or checking in with me. In the course of that discussion he was a bit evasive about how much they and how often they test but he did say that they add acid every week. Is there any valid reason to just toss acid in every single week? The numbers I found when starting to test on my own are below. I suspect that the super low alkalinity is the result of all that acid. From what I read, my water should be cloudy with all that calcium but it's actually been fine to look at (although flakes everywhere on the floor of the pool).
I'm hoping to be able to keep the pool service as I need regular visits and cleaning and inspection. Can I tell him to stop with all the acid now that we are almost ideally balanced? I've been adding it myself to get the TA down after the re-fill as it was 120 from the fill water. But it seems like that ought to be sort of stable once I get it right, yes?
Water Chem Before Re-fill:
FC - 2.35
TC - 2.99
pH - 6.7
TA - 40
CH - 900
CyA - 18
Salt - 4000
Thanks much,
