I have tested the RO
water and it comes out zero. I don't have a RO
unit at home so I get my water at our local watermill. I took it to my lfs
and they tested it also and said it is very good water. I guess I will keep doing what I'm doing and hopefully the nitrates will continue to drop. Like I said everyone is healthy and happy so I won't stress out too much right now. Has anyone used that aquarpure denitrator? I would be nervous spending $200 on that thing without talking to someone who has had success with it. THanks!
