Just ordered the tf100 this am
Excellent choice that you will not regret.
Without proper test results it is going to be hard to tell you
exactly what to add.
Would you be able to go to your pool $tore and have them check for metals? This will give us an idea of the severity of metals.
Don't let them talk you into buying anything, unless it's liquid chlorine.
Also could you please add your pool info to your signature?

This will help others answer questions about your pool, without having to dig through the thread to find the info, like I just had to do to see that it is a 16 x 28 pool of unknown depth.
If the pool is a rectangle with 48 inches of average depth it holds 14,400 gallons.
If the pool is oval, at that same depth it would be 12,700 gallons.
For either configuration, it will take approx. 20oz of 8.25% sodium hypochlorite (aka laundry bleach) to raise your FC by 1ppm
I would continue to add 1/2 to 2/3 of a gallon (64-86oz) daily until your test kit arrives. Once you get your test kit please post a complete set of test results including:
FC
CC
pH
TA
CH
CYA

Once we have that info, along with your copper test result, accurate decisions can be made.
