Hello, everyone. I've been lurking around the forums for some time now, and while I've gathered a lot of good information, I'm still struggling with my pool this year (2nd year of owning it). I'm cursed with the iron staining problem, and I feel like the pool store is just milking my wallet.
My pool is 12,000 gallons, in-ground, sand filter, and filled with municipal water (no iron indicated in tests).
Test Results:
FC .99
TC 1.49
CC .5
pH 7.6
TA 51
CH 129
CYA 26
Copper/Iron/Manganese 0
Phosphates 3579
I followed the AA treatment guide on here twice, and the stains returned both times. It happens when I start to bring the chlorine back to the correct levels. I'm confused, because the pool store and my own tests are showing no iron in the water. They now have me pumping $55 bottles of phosphate remover into the pool, and it's going to be an extremely expensive treatment, if I keep that up. Though, it does collect a lot of rust colored material and drops it to the bottom of the pool to be vacuumed out.
Please help me! I've been at this since late April. I have a pretty basic understanding of pool chemistry, so forgive my ignorance.
