I'm a first time pool owner as of October 2020. Things had been going okay and the water was clear until last weekend. I spent some time brushing, emptying baskets, and added some chlorine. A few hours later I notice that the pool was cloudy and had a green color, it has since gotten greener.
A friend of mine, who recently successfully SLAMed his pool, offered to help. Last night we tested the water, he has the TF-100 and I have the K-2006C, here are the results:
FC 0.5
pH 8.2
TA 130
CH 275
CYA 110
I believe temperature is about 55
My main question is surrounding what seems like an extremely high CYA. We used the pool math calculator which says I need to add 15 gallons of 10% chlorine to reach the SLAM target FC of 43. I would honestly prefer to spend a few hundred dollars on chlorine than have to drain and refill a significant portion of the pool to bring the CYA way down. Am I missing anything here? Can I just SLAM the pool and then gradually bring the CYA down while still safely using the pool?
We did add one gallon of acid last night.
