I just want to check that I am adding the correct amount of Muriatic acid to lower my alkalinity. Current measurement is 210ppm. The hot tub is 191 gallon. Using the Taylor table I see I need to add ~5.1oz total Muriatic acid. First adding 2.5oz and then 1.2oz and so on until TA equals ~100ppm. Am I correct? Thanks, Autoeng
Greetings, I have been reading the forum for about an hour looking for a solution to the problem in my mom's above ground, easy set pool. It's going crazy with algae and she wants to shock it but the chemistry is all out of norm. I think I have a plan, but would like to double check and get some advice. Here's the lowdown: Pool Type Intex easyset pool: 15'x4' 4440 gallons (though not quite full, maybe around 4000 gallons) SWG- intex brand (I think, it's from Walmart) Levels CYA 150 TA >240 PH >8.4 FC 0 Hardness 1000 Salt 8.0- 6140ppm (I'm transcribing exactly how my mom sent the values, not sure what the two different values mean here, but it seems high nonetheless) edit: tested with HTH 6 in 1 test kit strips. Misc info She has the SWG running from 8pm-11pm nightly like the book recommends. We have very hard well water with high pH (our area has a lot of limestone) My mom runs a water softening unit that also uses salt and the water that filled the pool went through this first. edit: she has never added anything to it except for the initial salt as instructed by the SWG booklet. Tentative Plan- please advise 1. Lower the CYA level by draining part of the water and refilling (but what if the well water is high in CYA? Maybe I should test it?) Also how much to drain? 1/2? 2. Add an acid to bring down the alkalinity. Which product is best for very alkaline/high pH well-water? 3. Add an acid to bring down the pH. Isn't this redundant? Use same product? 4. Brush the pool. Seems self-explanatory. 5. Shock the pool. Which product do you advise for use with SWG? 6. Vacuum the pool. Advice on a vacuum for an AGP would be appreciated, we don't have one. Thanks in advance!
