Ok, so I just orderd the tf100 this morning, a few years too late...but in the mean time my pool is cloudy with stains. Im new here so I will begin by saying I have a 14x 32 free form fiberglass pool with p4 aqua logic system and a hayward sand filter. No real problems for the 5 years I have had it except for stains that come off with stain treat of some sort, this year is a different story. Here is what I have done so far, my pool was crystal clear except for some staining from over the winter I ordered some ascorbic acid from a site listed on a forum here and followed the directions, and wow the stains were gone and my pool looked brand new!! Then about a week later my water started to cloud not green but just cloudy, I had the water tested (at ace hardware) they were unable to test the salt and unable to print results (I know) but they told me my CH was low, CYA low, PH right, and my FC was 0. I had just added bleach a couple days before because we had alot of swimmers over the weekend. Something didnt sound right so I went with my only other option, the pool store (I know) here is the results from the same sample TC 3.0, FC 2.6, PH 7.7, TA 50, CYA 30, SALT 2900(my reading 3100). I bought 8lbs CH, 2lbs CYA, and I already had baking soda. after adding these 3 things this morning my pool is yuck, not green but brownish staining on walls, seats, steps. I know my tf100 is on its way, but some advise would help me from going off the deep end and filling in the pool, THANKS.
