Is 15 percent bleach safe in pools?

A 15 percent bleach solution is not safe for use in pools. Most pool sanitization requires a much lower concentration of chlorine, typically around 1-3 parts per million (ppm). Using a high concentration like 15 percent can lead to skin and eye irritation, damage pool equipment, and disrupt the water balance. It's essential to use pool-specific chemicals that are designed for safe sanitation.
