Hot Tub Sanitizing Systems – Mineral Systems
Mineral systems use metals such as copper, zinc, or silver to cleanse the water. Water treated with a mineral system tends to feel better on the skin, as apposed to other sanitizers. These minerals kill bacteria slowly and without the use of electricity.
Mineral systems will not get the job done on their own. They require a small dose of chlorine or bromine, depending on the minerals being used. Chlorine requires 1ppm while bromine requires 2ppm. Mineral systems also require a shock to burn off organic waste killed by the minerals. We recommend using a chelating agent to prevent staining by the minerals in the hot tub.
Minerals are contained in a small dispenser which fits into most spa filters. However, some mineral systems require it to be installed directly into the plumbing of your hot tub. It is a simple, inexpensive installation which we can do at Central Jersey Pools.
Always test your hot tub for chlorine or bromine levels before using the tub, or at least twice per week. Mineral systems are not compatible with biguanide, and some are not compatible with bromine. Some minerals work as long as half a year. After that the canister will need to be replaced.
Some floating dispensers dispense both bromine and minerals.
