We are shocking using the slam method for mustard algae and we are not making progress after about 32 hours. Chlorine just dropped in the few hours we were at a baseball game after holding for most the day. I’m even using a bit higher amount of chlorine to try to beat it. Our alkalinity will not lower below 150. I continue to add muriatic acid but it stays consistent. Running jets to maintain PH. Water is very cloudy and light to sometimes dark yellow over white steps. We are brushing the sides and vacuuming once or twice a Day. Water appeared to start to look bluish this morning when at 40 FC but it’s back to yellow/green tonight.
FC was 26 just added enough for 40 to get us thru night
CYA 50
Alk 150
Calcium 300
Ph was 7.4, now 7.0 so turned jets on again
Thanks for the help
