A little bacgkround -
We purchased the house 4 years ago, and converted it to salt that very next spring. Within 1 year, I had replaced *every single piece of equipment*. The only thing that wasn't replaced was a the plumbing. Fast forward to the end of last year's swimming season - the chlorine generator died. During the death of the chlorine generator, I noticed a brownish cloud from the jets whenever I completed backwashing. The pool turned an awful color of blackish green over the winter and nothing I could do could get the pool to clear up. I did notice that the pool was almost completely crystal clear when the pressure in the filter got high and the water slowed down. I then began vacuuming the pool to get as much gack off the bottom of the pool as possible. What I was left with, is a pool that is now horribly infested with mustard algae (or so we were informed when we hired a pool company to come help get the pool opened for the season).
We are in the process of selling our house now, and relocating to Central Texas. I am only home on the weekends, and I have enough other things that require my attention that we opted for said company to open the pool. The pool company's representative came out and promptly informed us that we have a mustard algae infestation and that the only thing that will kill mustard algae is chelated copper. This was two weeks ago. He poured a couple of bottles of chelated copper algeacide in the pool, and said that the mustard should be dead in a day or so. Two full weeks and six bottles later, all we have is a pool that's blue, and when I sweep the steps and sides, I get an awful yellow/brown cloud that mushrooms out into the water. We have spent a FORTUNE in chemicals and we no closer to being open than when we started. A few minutes of reading on this site and I saw several people with mustard algae, and they were able to beat it.
We had a water sample taken and processed yesterday:
Total chlorine 14.6
Free Chlorine 10.5
Total alkalinity 98
Adj. Alkalinity 80
Total hardness 411
We put in chemicals per their instructions yesterday to adjust the Ph. They instructed us to put int Scale inhibitor, smart shock and 'pool tonic'.
I am sick of spending a fortune on products that aren't working. Can someone PLEASE help me fix my pool?
