A trip the ER?
I do know that some of the BC can cause bleeding. That's just one thing to be aware of.
Hadoken, have you checked your filter? Sometimes, if a filter hasn't been rinsed lately, it'll cause bubbles like that. Especially Aquaclears.
One 3 gallon tank, 2 bamboo plants, one sponge filter, one betta, a handful of salvinia. How the heck can the thing be covered in algae?!?!
Micho, use a razor blade or an algae scraper to try and get the hard water stains off.
EDIT: I don't want kids. EVER. When I was having an xray done and the guy handed me the lead sheet to protect myself, I almost tossed it away.
