Hard water quality questions
I'm on a well without a softener. I did a test with my water today and filled a 5 gallon tank with straight water and let it sit. It turns yellow after about a half hour. I read this is ferrous iron. I'm starting a new tank with fluval stratum and some plants I ordered and I'm wondering if I should use this water at all. I'm tempted to just use city water from my girlfriends house in which her fish are fine, plants ok too.
What do you guys think? The kh is 200ppm. Could the water actually be beneficial with a mix of RO? I don't want kill these plants that are coming but in the long run hauling water would become annoying when I need to do changes. I'm getting an aquaclear 20 filter for this tank and I'm wondering if that'll clear the water. Thanks.
