I recently had an acid soak/bath performed by my pool builder, at our request due to calcium buildup over the last 1.5 years. Since I maintained the pool from 3rd month until now, the scale buildup was a result at least partially to mostly from not managing the water balance.
Pool is 10,000 ish gallons, quartzscapes pool, and stonescapes seat, sundeck and spa.
When we started the process, the pool quartzscapes felt mostly smooth as expected, and the stonescapes was an aggregate feel.
Now the pool feels mostly like the stonescapes, as the aggregate is mostly exposed.
The first day the pool builder isolated the spa and heater, and added 28 gallons of muriatic acid.
The following day builder asked how it looked, i said it looked great reverse the acid process. He added (unknown quantity) of sodium bicarb, a sequestering agent, and a half gallon? jug of (pool startup) not sure what it was.
My questions are.
Since i tested the water after he left, and the PH seemed well below 6.8 still, shouldnt he have added sodium carbonate to bring up PH as well?
I tested multiple days PH and TA. and for 8 days PH was well below 6.8 and TA was 0-10,few more days builder added sodium bicarb, on the 9th day i finally had a PH of 7 and TA of 90. FC was 0-5 throughout, and CH was so high I could not measure it at one point, my question here is, was the PH andTA being that low continuing to eat the plaster and plumbing?
In the spa since it the only part i have sat in sice the job there is a good bit of aggregate sitting on the bottom of the spa from the stonescapes, and i have noticed on the spa overflow it seems to be missing some mortar in a couple places. My question is how much aggregate should come off of a stonescapes surface with an acid soak/bath, and should mortar be missing?
Now that i have asked my builder to take action with the rough pool surface he is telling me he can drain the pool and polish the roughness out instead of replastering, is this an action that works successfully, or looks good?
Overall i am really concerned about the integrity of the plaster at this point. The day the pool builder came to neutralize the acid, the surface felt pretty good, a few days later you could wipe some aggregate off with your hand, but after a week and brushing, the aggregate is really all that you seems to feel.
Any ideas or opinions welcomed, and sorry for such a long post.
thank you.
