Thanks to this fantastic site, I've kept my pool pristine all summer. Then I went away for a week. And the pump was left off. Ugh. Now I have this green monster.
Results:

FC 0
PH 8.5
CYA 20

I am following Pool Math with stabilizer in a sock, etc...added Chlorine.

And of course I have people coming on Monday. To swim. Any other suggestions? Thanks in advance.

Did you lower your pH to 7.2?

If you add chlorine every hour or two and brush brush brush you might be OK to swim by Monday. Just needs to be clear enough to see the bottom of the pool.

Test your FC at least 3-4 times per day and every couple hours if you can. Add chlorine to get back to your SLAM level FC.

I've replaced the gauge twice and I still can't get it to read anything. We are too far away from any pool companies. I am the designated "pool pump expert" but the gauge has stymied me.

Post a picture of it. Should be a standard gauge. The one I linked to is a quality gauge. If you need testing reagents, you can get those at the same time.
