We were out of town for two weeks - I'll skip the details but we came back to the water level being about 8 inches low and the water looking like pond scum. I filled it back up so that the pump could run, but it wouldn't prime. That's when I noticed that I had a busted PVC pipe right where it comes out of the ground (we had a kid mow while we were gone, so I assume he hit it with the mower). I fixed the pipe and started the pump running early yesterday. We have a nearly 30k gallon salt pool, which I normally shock with Chlor-brite, so I put 4 lbs of that in it and kept it running over night with regular brushings. Last night I was getting a fairly high chlorine reading, but just now when I checked it it is reading nearly zero. Just a faint hint of a yellow hue. It was running in super-chlorinate mode, so it should have been generating more chlorine as it ran. The pool is much clearer, just a little opaque but I can at least see the bottom now. Just trying to get it to fully clear up so I can use it. What would cause the chlorine level to drop so much in a day after putting that much in? Should I add more to finish the job?
