I think it's about time for me to do my first drain of my pool. Had pool for 4 years and been doing the BBB thing, water has been great. Well anyhow the pool has lots of staining and I want to make it look nice and new again, the only way I know to do this is to drain and do acid wash. I heard something about in-pool acid wash though. What would that entail?
Also CH is going over 1000ppm, so scaling is getting hard to keep down. Using the BBB method when I refill the pool I know I want my borates back and I will need to add CYA for sure as I like it around 60-70. What should I balance 1st? CYA? or just balance everything but borates all at once?
