The short version

Chlorine spends itself breaking down organic material such as sunscreen, sweat and body oils, which is why a busy pool needs so much of it. Enzymes break those down instead, which lowers chlorine demand and removes the scum line. Use enzymes in heavily used pools; shock to deal with combined chlorine, which enzymes do not address.

Frequently Asked Questions

What is combined chlorine?

Chlorine that has reacted with contaminants and is no longer effective. It causes the strong chlorine smell and stinging eyes, and shocking is what breaks it down. Enzymes reduce how much forms in the first place.

Do enzymes let me use less chlorine?

They reduce demand, so you may add less to hold the same residual. They do not lower the residual you should maintain, which is set by the sanitiser requirement rather than by convenience.

Is a scum line just cosmetic?

It is a visible sign of organic load, which is also consuming chlorine invisibly. Cleaning the tile line and reducing the load addresses both.
