Hello everyone. First post. A little background first:
I have been directed to this forum from a very knowledgeable member of TFP. Shout out to chem geek.
Ok, so here we go, I just bought a new house and it came with a anthony sylvan pool with spa, and waterfall from spa to pool. The pool is oval but not a mirror image so it's hard to get a solid volume. I'm guessing around 25000 when using the pool calculator. I have a diving board and the deep end is 8ft. rounded sides. When I first opened the pool there were a lot of problems. First it wasn't opened correctly and I didn't know enough to get the valves and everything in order. Anyway, old news.
I now have a new problem. The water is crystal clear but tinted green the morning after shocking. This week I was gone for 2 days. Each day my gf put in a gallon of 10% chlorinator. When I came back last night the water was still really clear but instead of a hint of green it was emerald.
So I shocked last night....went through 26 182oz 6% bleach jugs. Today I bought another 31. I put 6 jugs in and a half hour later checked the FC level. It was over 5ppm with my Taylor 2005 kit, the highest it reads, I tried the distilled water dilution method 1 part water 2 parts distilled water but the color was at the 1ppm mark meaning 3ppm???
I asked the pool store for a 2006 and they asked why I wanted that one. I said I wanted to read FC readings over 5ppm. They laughed at me and said no one should ever do that, HA! Anyway, since then I've ordered the TF-100 but it's not here yet. My pool is absolutely covered in shade by 2pm, so I started this test at 3pm. If anyone has any ideas let me know. I've been reading all types of threads in this forum for the past 3 weeks.
I have the two skimmers, pool main drain at bottom of deepend, and the Rayvac automatic pool cleaner running. Just did a fresh DE backwash and added it 6-7 more lbs of DE last night.
My levels are (30mins after dumping 6% 182oz jugs):
TA : 150
Total Hardness: N/A on my test kit. I drop the 5 drops of indicator in and it's already the color it should be when I'm supposed the count the drops of the titrant. Pool store measured it at 350.
PH : 7.2
CYA : 40-50. Pool store measured it at 80.
Pool is super clear, no signs of algae or spots in pool, but green.
Also, I had a nature2 cartridge left from the previous owners for 45k gallons installed but about a week ago I bypassed it thinking it was making the color green because of metals.
Sorry for the burst of information but thought I would let it all out before anyone asked.
Main question is why the dilution method doesn't show me over 15ppm. According to the pool calculator I should have > 20ppm in the pool right now.
Thanks a lot!
