1. Do all chlorine tabs have CYA in them?
2. Do all forms of CYA accumulate, or just CYA from chlorine tabs in a floater?
3. How much chlorine is actually put into the water by tabs in a single floater? It has 4-5 tabs in it. Does it just depend on how much the pool needs the chlorine or do the tabs dissolve at the same rate no matter what?
