Your chemistry is ok. It can use a bit of tweaking.Isnt this supposed to be easy?
These are my latest results. I think some of the numbers are starting to come right or i could be completely wrong? Any advise?
Your FC is high. FC/CYA Chart shows your FC target should be 6.
What is your SWG % and pump runtime? Reduce your SWG % to close to 0 and let your FC fall.
pH testing is invalid when FC is over 10. See Taylor pH Test is Unreliable When FC >10 So don't adjust pH until FC is below 10 and you get a good reading.
