Greetings everyone,
New member and TF-100 owner. Having a very strange year to say the least pool-wise. Every year I open my 20,000 gallon pool and clean it out (porous safety cover), and take a sample to the pool store to be analyzed. Opening this year was harder than usual, having an algae skin on the bottom & walls that took much effort to scrape off. On 5/22 took my sample to the store and got my results of FC-10.0ppm, TC- >10ppm, CC- 0ppm, PH- <6.5, Hardness- 140 ppm, TA- 0ppm, CYA- 85 ppm, no copper or iron, phosphate- 1000. They gave me 39# of Alka to add, plus 16 # Cal the next day. Took a sample again on 6/5, and got FC- >10ppm, TC- >10ppm, CC-0, PH- 6.7, Hardness- 150 ppm, TA- 100 ppm, CYA- 80 ppm, Copper- .28 ppm, no iron, Phosphate- 1000. They said add 9# Alka & 10# Cal. Also after the 1st visit after adding the chems I started getting yellow staining on the plastics and liner in the pool. I added their Pool Stain Treat stuff (Oxalic Acid) a few times, and it still didn't go away. I read about the Ascorbic Acid on here and found a pool place that carried it, and needed 4# and 24 hrs to clean it up pretty well(Funny, nothing on the bottle saying it contained Ascorbic Acid, but once put on the stain it went away like magic!). I added 1lb bag of Shock (Pool Brand from Sams) 2 days ago when I noticed some algae starting. Whe have had temps in the 90's for about a week. Cleaning the pool today, I notice the stain starting a comeback. I made a mental note to buy more acid, but took out the TF-100 and did some tests. Results- FC- 19, CC- 1, TC- 20, PH- 6.8, TA- 180. I use Tri-Clor 3" tabs from Sams in an in-line chlorinator usually set on #2, and run the filter 8-12 hrs daily. Also use Algaecide 40 (Alkyl) from Sams, too. Was looking around at Target & Walmart for Poly 60, but the brands they carry use Alkyl. My water is clear, but with the staining coming back, and the chem readings I got today, I feel I'm close to a disaster! HELP!!
Thanks, Bob
PS- Also get maple & black walnut leaves in the pool if that has any bearing......
