Cleaning up algae and water mold in a Intex AG pool after vacation

[strat]

Ah -- OK. I already replaced one, but it was the control board, not the cell. It's a project in my garage. ;-)

Oh, yes. Those projects you're gonna get done when you get around to it. I've got some of those. But I still haven't gotten the projects done.

However, I do have a nice round tuit:

PoolDoc, thanks for the tip -- after three days the Cl snapped back and the water's crystal clear again.

New numbers:

Free Cl = 5.8
Combined Cl = 0.2
Total Cl (OTO) = 3.0
pH = 7.4
Alkalinity = 120
Cya = 70 +
NaCl = 3000

(The pH dropped to 7.0 when I added cyanuric acid and I bumped it back up with borax)

I'll keep adding bleach for a week like you suggested so I don't have a recurrence (just added an extra pint this morning because I expect a heavy swimmer load for the 4th).

Strat,
Use a 10mL sample when you test instead of a 25mL one. It will make your testing reagents last longer.
