What's your favorite testing kit? Maybe one with money being no object and one that's the best bang for the buck. I went to shock the pool today and the instructions were dealing with things I don't think my basic little kit even measures. Also your best resource for coming up with a system, a preferred method to keep it all clean and balanced. No really interested in YOUR method, just where you went to learn about it.
Pool School at start-up has got me this this far with a basic testing kit and some muriatic acid and chlorine tabs far but the more I read about it the more I find alternate methods, opinions, and other things to consider that I haven't even learned about yet. How often to shock, which products to shock with, etc.. CYA (wtf is that?), free chlorine vs residual vs total, etc, alkalinity increasers...
I hear a lot about TFP, but they have their detractors too apparently. Where should a newbie go to un-muddy the waters, so to speak.
