List of abbreviations?
Ok, so I'm trying to read through a lot of posts and I keep coming across abbreviations that I have no idea what they mean..sometimes I can figure it out..sometimes I can't. I keep seeing things like HOB (hang off back?), PH (powerhead? not pH), PC (no idea..some sort of light?) and a bunch of other terms. Is there any article or "cheat sheet" that might list all the various abbreviations and acronyms and whatnot?
Thanks!
