CYA Disappears in Summer

[mguzzy]

This is news to me that cya degrades over summer. I thought the whole point of using liquid chlorine was to avoid adding cya because it never leaves the water and requires a partial drain to remove. So it requires monthly additions of cya in hot regions?

The whole point of using liquid chlorine is to avoid adding TOO MUCH CYA when using Pucks. You still need some to protect the chlorine, from UV. But CYA does degrade in higher water temps and UV. I usually have to give my CYA a "boost" around mid summer.

Use a turkey baster. Or this.

Just weight the end of the tubing so it will sink under the water.
