The 'BBB' method is more symbolic then literal. It's true we recommend a lot of bleach and borax. Baking soda? Not so much: people usually don't need more "total alkalinity". But if you look at my "Super Simple" recipe for Intex type pools, you'll see that it's a dichlor + borax method. When we refer to the "BBB method", we just mean using the best way we can find to care for your pool, without regard to brands, pool industry hype, or 'new & cool' pool stuff.
In your case, because I don't yet know how much CYA (chlorine stabilizer) you have in your pool, I'm recommending bleach. You can get it pretty much anywhere, and it won't add stabilizer. IF we find your stabilizer is low and IF you have access to a Sams Club, I'll probably recommend that you buy some of their dichlor, which is well-priced and not diluted or blended, unlike what's sold at Walmart.
So yes, for now, add bleach daily.
You can go to Walmart and get a cheapo OTO/phenol red kit (the K1000 is slightly better version), and use it to test pH and chlorine now. That wouldn't be a bad idea if you think it's going to take a week to get any of the ordered kits.
