I have been struggling to get my pool to desired FC levels. Just started up a new SW system which is working properly. over the past week I have added 15 lbs of Bioguard super soluble, no real effect, then 4 lbs (3 days ago) and 3 lbs of in the swim shock last night. FC this morning under 1.
CYA was 89 when tested at the pool store; I measure around 120 after adding the super soluble (I have a Taylor test kit). Phosphates measure 4000ppb.
The support people at Circupool (SW generator provider) are advising that the phosphates are a big problem as well as the CYA. I will be removing the phosphates this weekend using PhosFree and/or Tr-10000.
I don't have a drain so in order to bring CYA down I will have to siphon. annoying but possible. My pool guy says CYA should be OK up to 200ppm, but everything I find here and elsewhere raises a flag over 100 and recommend around 70 for SW pools.
any advice is much appreciated. I'm getting tired of chasing my tail!
