Adding 2 lbs. to your pool should have added about 30ppm of CYA. It may be that it hasn't fully dissolved. I'd wait 3 days or so and test it again. If it is still only 10ppm, then you'll want to add a little more or you're going to have a hard time keeping chlorine in the pool especially on a hot, sunny day. Keep the chlorine levels up for another day or so. Test tonight an hour after you add bleach and note the reading. Then, test again in the morning within 2 hours of sunrise. If you have lost no more than 1ppm of chlorine, then you'll be in good shape. If you lost more than 1ppm, you'll need to shock it back up. Continue this cycle until you don't lose more than 1ppm of cl overnight.
Another thing you'll want to work on after you get your pool holding chlorine is lowering the alk. I'm going to go ahead and post the link so you can start reading about that process.
