I just bought a house that has an IG pool. It is a vinyl liner pool that holds between 18500 to 19000 gallons. The previous owner used the nature2 system with an inline chlorinator. After reading posts on this sight, I have taken out the cartridge in the nature2 and turned off the inline chlorinator. I went to a pool store about a week ago to have them check the pool water and this was there result.

FC: 0 PH: 6.8 TA: 100 CYA: 25 CH: 180 TDS: 600 Copper/Iron: 0 Phosphates: 200

I have since tried to use the bbb method to balance the water by adding 6% bleach and using borax. I can't seem to keep chlorine in the pool very long. So far every night when I check the water the chlorine levels have been around .5 to 1 ppm. I keep adding a whole bottle of bleach to bring up the chlorine but by the next day, most of the chlorine is back to .5 to 1 ppm. I have purchased the test kits that are recommended on this site and this is the test results I got about 20 min ago.

FC: .2 ppm CC .4 ppm pH: 7.0 TA: 30 ppm CYA: 50-55 ppm

I would love to know what I should add and in what order. I have purchased more Borax, 6% bleach, and 12.5% bleach. I still need to buy acid. I greatly appreciate any help.
