Ugh.
So I went on vacation for 11 days, and I came back to a slightly green pool with drains that are barely visible. There's also some brown stuff on the bottom that I believe is algae because it's in the deep end, which is in the shade some of the day, whereas the shallow end gets sun all day long. At first I figured the other guy just hadn't been keeping up with it. And then I tested the water and learned that was only half the problem.
FC: 2.5
CC: 1.5
TC: 4.0
pH: 6.8
CYA: 180
TA: 210
Keep in mind that I had gotten the CYA down to about 80, which is still higher than recommended, but at least within legal limits. So I started to wonder how the heck this happened. It didn't take long. I opened up the mechanical room, and gleaming right in front of me were several huge buckets of
dichlor and trichlor.
I opened the feeder tube and sure enough, it was full to the top with trichlor tablets with the valve set to 4, and the pool log indicated that he "shocked" (in his definition) the pool right after I left for vacation for some unknown reason. He added a total of
12 pounds of dichlor in two days, and then for the other nine days, he added nothing. And apparently did nothing else.
And I should clarify that there was still plenty of plain old bleach in the cabinet, so it's not like he ran out of it or anything. He just refuses to get on board with me.
This is extremely frustrating. On the bright side, I now know where to start based on my previous experience. :-D
I closed the pool down today because it's just not safe to swim in it. I am not adding anything at this point because it's obvious that I'm going to need to drain and refill about 75% of the water once again just to take care of the CYA level. Since the pool will be closed today, I will be able to get a head start on the drain/refill at about 6 p.m. (rather than 9, when the pool closes usually). Of course, then I will need to shock the pool and clean it, etc., etc. Luckily our city guidelines allow swimming in up to 10ppm FC (they figure since people eat off dishes in restaurants that are typically sanitized in 100ppm, it's safe to swim in 10% of that). So, I don't have to let FC fall too far before I reopen it, so long as the other requirements are all met.
And for those who wondered when this post was active before, yes, the pool I run is considered a public pool.
I'll post more results and take a couple pics before I begin the D&R process tonight.
:super: Here I come to save the day (again)...
It is very satisfying to see someone take a pool in need of help and make such a dramatic improvement in a matter of days. Hat's off to your perseverance in persuading your property manager. Both of you will reap the benefits.
