I did the testing.
Checked it twice.
FC I recorded as 0 because the color was more faint than the minimal 0.5 on the 2006 kit. I suppose 0 is not actually true. But less than 0.5
I figure CC as TC-FC or was it the other way around. Its written down. lol
I have a 15,500 gallon pool
Solar Panels up a rise to the roof
auto cleaner running on the main pipe line
1.5 hp pump
Hayward C900 filter pump
Concrete with diamond brite surface
skimmer and lower drain and 1 intake for auto vaccuum
My cya was well above 100 had to drain and fill 3 times to get it to 60. 2/3 2/3 then 1/2 volume of pool
I made a mistake and used pucks and powder - NEVER AGAIN
These numbers are after the fills without any chemicals added. 2 hours circulating the water
Right now the water is clear and you can see well to the bottom although I think it looks just a very slight brown green. It dosent sparlke. No alge present on the sides.
The filter is clean at this time. I have rinsed and cleansed 3 times this week during the drain and refills
The pool store says I need to shock it every week raising the level to 15 then let if fall and do it all again. They also wanted to sell me Calcium to add, I said not at this time.
So here I am I am leaning on a shock as the water isnt as fresh looking as it should be. I did not test it for metals but being greenish brown I would think its alge in the water?
Oh yes they did also want me to buy some metal out, again I said no untill I know what I am dealing with.
Thanks everyone hope this helps you help me
