Here you can ask questions (myth or not myth?) or post your own debunked saltwater myths!
I'll start it off:
You can't convert a saltwater tank to a freshwater tank or vice versa.
This is wrong. You can, and it's really easy. You basically just need to rinse and wipe the tank out. You have to be more thorough if you're converting from saltwater to freshwater though - obviously you don't want any residue salt in a freshwater tank!
