This right here gets me. Look at the bad rap that salt pools get from improper maintenance. Cough, cough….. Texas…. Cough. At least a chunk of the spa issues have to be similar. Some wahoo ‘nuked’ the hot tub, with like 5 bags of shock, when the pool store couldn’t help.
Or also just like pools, poor quality materials didn’t stand a chance either way, no matter what markup the customer paid.
But the salt always takes the blame. I do believe it causes more of an issue in hot tubs for the quality issues but I’m still not sold that I’d care if given the chance.
