Frustratedpoolmom,
What do you mean by "pool frog"?
The Pool Frog is a an Ionizer, similar to your Nature 2. I lived with the darn thing for 5 seasons, what I nightmare. If I knew then what I know now, never would have put it in, I would have saved myself hundreds of dollars and lots of headache....but then I might not have found TFP....
I saw your Slideshow photo from February...very nice indeed! So it is hard to tell from the new pics if its a clarity or cloud issue, and I can see why Dave thinks it's clarity. Your test results will provide alot of info there.
About the third year of using my Frog, those kind of stains showed up in my pool. Looked the same as yours, sort of dark tan, yellowish-brown. Pool Store told me it was Black Algae (it wasn't)...VERY long story short... by the end of my first season with BBB, the stains had slowly faded away, never to return. I suspect they were a result of my water being out of balance, and once it was maintained properly, they didn't return.
So, if you haven't been maintaining a high enough level of FC, in relation to whatever your CYA level is...it is entirely possible those stains are organic, as was my case. You can try my earlier advice to determine the type of stain, chlorine tablet/stick/puck on the stain or try vitamin C.
What is still interesting to me is the earlier comment that they had you put in metal sequesterant. If metals were present at one time, routine maintenance dosing of the solution is usually required to keep the metals in solution and not on your pool surface. So I wonder if they determined you had metals present?
It's a lot to take in, I know and I too am sorry if we are getting off-topic now and then.
