Hi - had a vicious case of algae and insanely high CYA (the CYA was around 300). Thanks to the advice in some great posts here, I have been doing a series of 20% drain and refills to knock it out. That part is almost done. After today's refill, I could see the bottom of the pool through the water. CYA was down to 100 and I'm finishing another 20% refill right now.
I would appreciate any advice or steps on how to "reboot" the pool once that is completed. I've had the pump off during the drains and refills and have not added any chemicals. At what point should I turn the pump back on? And once I'm ready to start rebalancing the chemicals, would this be a good order?
1 - stabilizer
2 - ph plus or minus as needed to get in the right range
3 - chlorine to get in the right range (I'm thinking just regular chlorine rather than shock to avoid CYA going crazy again, but please let me know if your experience varies)
4 - clarifier
5 - algaecide to help avoid this happening again
Thanks in advance. Cheers.
