My first post...
I am preparing to drain and refill my pool due to sky high TA and CYA levels. I had a couple of questions on this:
1) Is it a good idea to always do a chlorine bath prior to refilling? The pool looks fairly clear except for some recent green at the water line that I suspect is due to low chlorine level. If this should be done, what is the recommended chlorine concentration to use, and what would the technique be? I've seen some videos where a watering can was used, followed by a simple hosing down with water. Is there anything else cleaning-wise one should consider while the pool is drained?
2) After the refill, what is the generally recommended order of doing things as far as chemicals go? By this, I'm wondering about the order for getting pH, chlorine, TA and CYA up to snuff. FWIW, I plan to use regular old bleach going forward to avoid the crazy CYA levels.
