I found out yesterday a trace of algae in my swimming pool. I check everyday the pool and do the test. On Monday show that I don't have any Chlorine, so I went to the poolmath input the numbers and I apply what I need to raise my chlorine ( 129oz) ok. On Tuesday numbers was ok. Wednesday is when I found out the algae. So I do all numbers again and this is was my result:
CH= 350 ppm
I know my CYA is high however was form 100+ to 75 that is the actual number.
Do my math is wrong ? I living in TX and the heat can cause the evaporation of Chlorine plus the high in CYA. Any suggestion will be appreciate. By the way the water is clean and crystal just some part of the wall show the algae.. Thank you...
