Hi all. Have bee having a slight problem with green algae. Started the shock process(per pool school) on Saturday.
Water is clear until I brush, then very slightly cloudy, still mostly clear.
Tested CYA - 40 (bought enough to raise it to 75 once shocking is complete)
Brought chlorine up to 17 per CYA-Chlorine chart
Stayed consistent with testing, adding chlorine (if needed) every 4 hours.
Brushed twice Saturday and twice Sunday.
Cleaned cartridge filter Saturday and Sunday afternoon
FC dropped overnight last night from 17 to 15. Brought back up to 17 before work this a.m.
Tested when I got home, dropped to 10 - added chlorine to 17 , brushed.
Please let me know if I'm doing this correctly.....
Now, my question is this: am I wasting time and money(chlorine) by only being able to test in the morning and at when I get home from work?
This is a great place and I have learned so much, thank you all!
