I opened Sunday, and to my surprise, the first time ever I had a CYA reading of 50.
I did not check CYA at end of year, assuming it was 70/80, but I did throw in some pucks for about the last three weeks so maybe that was the cause.

I waited about a week to long to open as water temp was 61
PH 7.3
FC .5

Salt 2400

I fixed the small leak at my filter drain, hooked everything up, took out all the plugs, and we were good to go.
Water level was good but dirty as always due to my mesh cover, have some algae growing on walls so ran Chlorine up to slam level (20) and brushed.
This am FC reading was 19.0, so hopefully a quick slam.
Now praying my robot is working as at end of last year it would not move when turning it on.
Taking it apart today to check it out.
