Hmmm - what's the 3? I'll take a cold guess and say copper, chlorine and stabilizer. Let me know if I'm wrong (or right). We don't recommend Copper in pools for a number of reasons - some are less of a problem in small pools that can be readily drained and refilled. Copper can stain pools, fingernails, and blond / colored hair green. It can also lead to an unsanitary pool that looks clean. Copper is much better at suppressing algae than killing bacteria.

If you have a filter, check out the stickies in the Pool Chemistry for Intex-type Pools forum. If not, take a look at Kiddie Pool Care - Guide to Kiddie Swimming Pool Care.
