My 25K in-ground pool was re-plastered with Pebble Fina last Friday, and I'm having trouble balancing the water. Plus I saw in one topic here that a freshly plastered pool might require different recommended levels? At any rate my first obstacle is the high PH. I've added 1.5 gallons of muriatic acid over the course of the last several days, and PH is still off the chart. (I used the 'green' muriatic acid first, and now I'm using the nasty full-strength stuff.) Tough to gauge how much more to put in when every reading is too high to measure. Any suggestions?
Next I'm going to need some CYA for this weekend's pool party, but I see that the solid should be added when back-flushing isn't necessary. But my fresh plaster requires constant brushing and back-flushing. How do I get around those conflicting requirements?
At first reading my TA was 60, and I was going to boost that once I get PH under control. Calcium is also low - about 50 - so I was going to start adding that too. I've been using a combination of bleach and tri-chlor tablets for chlorination - partly to get the CYA up a little with the tablets because the pool is exposed to direct sunlight much of the day.
Any advice appreciated.
