Local pool store is pushing these to customers like an aggressive car salesman selling used cars at the end of the month. I am floating these things in my pool and am wondering if these also cause CYA issues. I searched TFP for this brand/label but did not find the specific detail. I'll remove today if these can cause more harm than good, my water is crystal clear (after recent drain and fill, and I generally keep the chlorine on the lower end of the spectrum, but after one week away = green algae that forced drain, liner scrub, and refill, local utility loves me for the water / sewer costs i incur.
Thanks for any advice, this site is great !
