It is a DPD test kit. Good or bad?

My TA was super high a few days ago. I lowered it using Acid and then bought a fountain aerator to bring the ph up. It worked beautifully.

When I was in Leslie's buying the test kit I heard the clerks muddling up another pool so when I had the chance, I scribbled www.poolforum.com on the back of my gum package and gave it to them. They were frustrated and getting pi**ed off at the clerk because he didn''t know what he was talking about.
They'll probably kick me out the next time I go back.

My first CYA reading was near 300 at the beginning of the summer.

pucks pucks and more pucks then treating it with bagged shock.

Thank goodness for this forum!
