It's that time, landlord had a pool guy come open it up. Pump up and running, 2gal chlorine & some pucks in, and a beautifully dark green swimming pool.
I'm woefully underprepared as he came earlier than expected. I have no chlorine and no R-0871 reagent. Yay :D

Already backwashed it once because it almost had no pressure 30-45mins after initially running. Yuck! I tried to test anyway but I know without my FAS-DPD it wont be accurate for chlorine. It's above 10 I know that haha!

Trying to remember a few of the things I learned last year for a smoother open. From my CYA test I'm getting practically no CYA at all. I think I closed with an estimated 40-50 CYA last year, so I guess it all just degraded over the winter? Also, pH test is inaccurate when at SLAM levels, yes?

For my sanity of a smooth open this is the game plan:

Get a ton of bottles of liquid chlorine ASAP, With 0 CYA keep FC levels above 10 or more to sanitize/slam.
Need to add CYA? Via powder shock? Or the chalky stuff.
Don't worry about pH until water is clear.
Backwash when pump pressure is low (I don't have a working gauge so I have to just watch the jets.)

Right now should just be adding chlorine and can focus on other chemicals when water is clear, yes?

Excited for another pool season and appreciate this forum!
