Some Questions Answered
Can These Tablets Be Used in Floating Chlorinators or Automatic Feeders?
Yes — you can use these tablets in floating chlorinators and many automatic feeders. Their 3″ slow-dissolving design suits float feeders and maintains steady sanitizer release, supporting feeder compatibility across pool types, including vinyl and salt systems. Individually wrapped tablets reduce handling exposure and preserve chlorine strength. You’ll get predictable dissolution up to a week per tablet, so you and your pool-care community can rely on consistent, clear water maintenance.
Are These Tablets Safe to Handle Without Gloves?
You shouldn’t handle them without gloves. You’ll reduce risk of skin irritation by using chemical-resistant gloves and protective eyewear when opening or placing tablets.
