Another "First water test" post

Been out of town for a while and not able to stay on top of everything. Just tested again and my FC is at 0. Gonna add some liquid chlorine to try to get it back to 3.

Even though it's near freezing outside, am I expected to lose chlorine from the sun in the winter still?

Yes, but much slower. Definitely increase the FC now though.

I must have some old chlorine. I put in enough to get my FC to 3.5 three days ago. Just tested and FC is only at 1.5. I guess it's a good thing it's too cold to swim.
