Being a newb ,I dont have a ro/di filter yet and I cheated and bought filtered ocean water from petco to start cycling a ten gallon nano.What water would you use to top off your tank should I trust the ro/di filter unit at the local grocer or by some bottled water (plus what kind) .I would be grateful for any advice.
Thanks
