I am new around here and recently received my TF-100 kit. I mainly bought this kit as I have been having trouble in the past 6 months keeping my pool clear, with a recent presence of black algae spots on a few of my steps and certain areas of the bottom of my pool (pebbletec finish). My previous kit was only testing TA, FC, pH. As of tonight, I ran a series of tests with my new kit. The results are below:
CYA = 120 (confirmed with a dilution test)
pH = 7.3
TA = 130-140
CH = 450
FC = 1.0
CC = 0.5
TC = 1.5
It was just as I figured... from reading these forums for a while I just knew my CYA would be through the roof, mainly because my previously normal "shocking" levels of liquid chlorine were not longer killing off the green ring algae around the edge of the pool, and it was staying cloudy. Also, because I have been using Trichlor pucks for over the past year of living in the house No idea what was being used prior to this with the previous owner.
Now is where I need some help:
- What is my priority?
- I would assume it is to get the CYA much lower by doing partial drains? Is this accomplished with repetitive backwashing? How much water do I have to drain out of the pool? I have a DE filter.
- At what point do I SLAM? I have never done this method before so it will be my first. How many gallons of bleach/liquid chlorine should I buy to have on hand??
- Question about OCLT:
- As I am performing the OCLT to determine chlorine usage, how often do I need to be present for testing throughout the day? I am frustrated because I will be gone Friday AM until Sunday evening this week for a wedding out of state. I work M-F from 9-5 otherwise. So, should I even attempt the SLAM and OCLT within the next week, or wait until the following weekend when I have more time to be around the house?? I am wondering if I should just keep dumping in a gallon of chlorine every day or other day until then just to keep things at bay?
HELP! Thank you!
