To avoid nuisance Algae from growing in your tank, it is wise to get Distilled or Reverse Osmosis De-Ionized water. You can often times buy this kind of water at the fish store where you found your saltwater pet. You can also buy RO and distilled water at your supermarket. One horrible thing to do is use tap water. It contains the nasties that are bad for your tank. Chlorine, Phosphate, Nitrate, Fluoride, etc. are common things found in tap water, but pure water helps keep things healthy.

I dont agree with that at all..... Stay away from Bottled Water... through there process they take away bad things, but they also take away good things that your fish need. Ive seen so many fish die because of this mistake... dont use bottled water.... you will just end up killing your fish... ;/

EDIT: uh...yeah.... folks, once you add the salt mix in, it's going to be HIGHLY mineralized, so distilled water is just fine.
