I have been a member for a few days and have been trying to follow your guidelines but have had no luck so far. I really am at the end of my rope. I have a 30,000 gal swamp in the back yard that my wife wants to drain. I have been working 12 hr days so I have not been able to get to the store for some real readings and I don't have the proper test kit yet, I should on Thursday.
Here's my set up:
30,000 gal. vinyl pool
Cristal Flo filter
New Zeosand in the filter
I have been attacking my pool all this week and have gotten nowhere. Without my CYA reading I feel like I am lost. I have been adding 3 -4 gal of 10% chlorine per day, sometimes more trying to get my chlorine levels to stay high as prescribed.
Could I be having some of this problem from my new Zeosand in the filterl I swapped out the sane myself because the water was cloudy (on advice of my 'pool expert salesman') .
I am heading to the store for the distilled water to see what readings I can get for chlorine. Maybe I just haven't gotten it to shock level.
This a rambling email because I am so lost on this. The summer will be over before I get this handled..
Please help, my wife (and I) can't take this swamp anymore!!!
