I'm a new pool owner, and I just took over from the "pool guys" after they opened the pool. 27k gallons, in-ground plaster, DE filter. I had armed myself with the TFP testing kit and read through pool school. When the pool guys were done, they left the pool as follows:
FC: 20 (same TC)
Figuring the pH needed to come up, and the pool might as well have some borates, I added 3 boxes of the 20-mule borax. The following day, the numbers were the same except pH now 7.5 and FC down to 17.
The curious part is that before I added the borax, the pool had been crystal clear for four or five days (prior to that, in the first few days after they pulled off the cover, it was variously green/cloudy). Now, over 24 hours later since adding the borax, it's cloudy. I can still see the drain at the bottom of the 8-foot-deep end, but just barely. Any thoughts on this? I read some threads that seemed to scoff at the idea that borax can cloud water, but I'm not sure what else changed.
I figure at this point, I'll maintain the chlorine and hope it clears up? Any other suggestions?
Thanks in advance...
