Adding BBB

[waterbear]

I wonder where can I get muriatic acid. Home Depot doesn't carry it. Hydrochloric Acid (the actual compound) is cheap - I wonder if chemical supply houses sell it to residential end users.

Often it is in the paint department. Also, you can usually find it at ACE or other hardware stores (once again if they don't have a pool dept. check the paint dept.) or at just about any pool supply store.
