We have a week long vacation scheduled for end of July in Florida. Lord knows it's gonna be HOT in Texas! My question concerns the use of cal-hypo tabs while we're gone vs. trichlor tabs. I have NEVER added any calcium to our fill water. Current tests only show it as around 60 ppm. Can these tabs be dssolved in the skimmer without any adverse effects such as the highly acidic trichlor tabs. I have a couple of floaters as well to fill. Any reason I should NOT consider cal-hypo tabs? Any one brand of them recommended over any others? Thanks!
