Be gentle, I'm new!
I have a newly build 17,000 gallon gunite chlorine pool. I have a pentair variable speed pump, and I'm using trichlor pucks in an automatic chlorinator. We took our first water sample to a pool store and here is what the readout said:
Total chlorine 1
Free chlorine .5
Total alkalinity 185
Total hardness 337
Everything else like metals and algae say zero or none.
I've gotten the pH down to around 7.2 but I'm adding 1/2 gallon of acid every other day. In between the pH creeps back up to 8.2. I've done some homework on here and I've been running my water features to bring up pH so I can add more acid to bring down my total alkalinity.
Heres my main question: The guy at the store (and our pool builder) said to shock it weekly. Last night I checked chlorine and it was 3.0 and i added acid to get the pool to 7.2. Then we cleaned out our DE filter (yuck!) and I poured in two bags of Bioguard burnout 35. I kept the filter running all night and this morning my chlorine was clear...like below 0.5. I check the auto chlorinator and I was out of pucks. Oops.
I think this means the pool wasn't shocked was it? My DH bough bioguard shock (24lbs) and like 25lbs of pucks. I want to try the BBB method, but DH got what you all lovingly called "pool stored" so we are using up what we have. I'm ordering a T-500 kit tomorrow but in the mean time...how much of the burnout 35 should I dump in, and how long until we can swim again?
