If you'll go to WalMart and buy the 6-way drop based kit they sell for around $15, it includes a CYA test and you can test it yourself. The problem with stabilizer (or any parameter) being "good", is that you don't know what they are comparing the "good" to. Stabilizer is stabilizer, and what level you have dictates what level of chlorine you have to keep in the pool to keep it clean. So without a good idea of what the stabilizer level is, you're just guessing when it comes to how much bleach to add. I would either get the other test kit and test it myself, or take your water sample to that store and one more, if possible, and have it tested again.
