Its not you, its them. Their testing is terrible and the advice is worse. We got you now.
As a follow up to this, I received an email from he store today stating she has on good advice from the chem rep that I just need to do the cycle of treatment plan a couple more times for results. I let her know we have tried this cycle more times than I can count and in this last occurrence it made the copper increase not decrease. I do think they mean well, in all honesty. But this is the definition of insanity.
Fyi, they're recommending, what we can refer to as the potion du jour; pool magnet plus, sparkle up, alkalinity, ph, and calcium. I know my pool needs a lot to get it where it needs to be. But it has failed numerous times and I am not insane. I'll let that be and move forward. I really appreciate you all. I am waiting for test kit to come tomorrow. Steady rain here, pump is 24 hr and backwashing as needed, per someone else I added 3/4 gal of liquid chlorine last night and will do the same tonight. Really glad, because it would be much worse without it due to the multiple days of rain.
Hope you all have a great day and are somewhere more sunny than I am.
