I had a pool company open my pool this past Wednesday. They fished the leaves off of the cover, removed the cover, added some algacide and chlorine, and the following day hooked up my SWG and told me to add 4 bags of salt after the filter had run 24 hours and been backwashed. I did that and my pool is a lovely shade of light, kool-aid green (but not cloudy). I tested and I am low on salt (3000 and the system wants 3400) and my chlorine and CYA levels are unreadable. I won't be able to get any instant CYA until tomorrow. Do I need to slam this pool, or do I just need to get the salt, CYA, and chlorine up to proper levels? TA is at 50; so I planned on adding baking soda to bring it up to around 70. I plan on adding the salt and baking soda this evening. Can I add chlorine as well without any CYA? Thanks for any advice.
