I was going to try calcium hydroxide, but couldn't find it in the grocery store (legs isn't open yet today). Does lemon juice really work? Also, won't that affect the rest of the tank?

Yes, it works. The caution is that you don't do too much of it at once in a smaller tank. As you're adding an acid to your tank. You can also try white vinegar, or kalk paste. You know you've hit the thing (if you're using a syringe) if the stalk starts to swell and turn purple!
