Is primo water from Walmart safe to use in the aquarium? Should I still add prime? I live in a 2nd story condo and don't have room for my own rodi unit unfortunately.
Is this a brand that is sold in the gallon jugs by you? I ran my reef off of the great value water for several years until I got my ro/di back up. Had algae from it, but wasn't much I could do about it.
This might not be something suitable, but until you can find a better option it might have to do. Distilled water will still be better than tap every day of the week.
