The 17 lbs of Balance pak they want you to add is what we use the baking soda for....however, if you're going to use any chlorination method except for trichlor/dichlor, your alk is fine where it is. If you're going to use trichlor tabs or dichlor powder for chlorination, then you'll want to bump it up some later, but you don't need to worry about baking soda at all for right now. Just follow Watermom's advice to keep the chlorine high and bump the pH up a little bit, while your CYA is dissolving.

The bleach that you added to your pool is killing the algae, but it's going to take filtering to remove it from the water. If you can keep your pump running 24/7 without danger of the skimmer getting clogged up, that's the best thing you can do, but watch your pressure gauge and make sure you're backwashing (sand or DE filter) or cleaning the cartridges (cartridge filter) when the pressure rises between 6 and 8 psi over your "clean" reading.
