+ You're fine.

+ Watch the K2006 videos, especially the hardness and CYA videos:

+ Don't think about bromine -- ignore any bromine results or calculations.

+ On an Intex, hardness doesn't matter, unless it's too high: your hardness is not too high.

+ You don't have any CYA, unless you have ALREADY used some dichlor or trichlor, or added stabilizer directly. (Watch the videos!)

+ All the tests, except the pH test, look for a major color change, rather than reading a tint. You *can* get a pH meter, if you really need one:

+ Relax! If the water's fairly clear and not green, and the sides aren't slippery/slimy (an early sign of algae) -- you'll be OK.
