I have a few nano reefs and due to my current living situation I can only use my rodi unit once a month or so when I actually am home for more than 2 hours at a time so I am wondering if my tap water is reading 100 tds but when its ran through a zero water filter it is zero tds can i use this to mix water change water and top offs half the time? the other half of the time would be with rodi water but i run out about halfway through the month and my work schedule makes it almost impossible to bring out the ro machine and actually run the water i need since i have to break it down every time i use it and drain it/pack it back up. With it removing most minerals, chlorine and heavy metals its got to be a better alternative than tap water right? price is not a concern i am aware they get used up quick and are expensive its just a ease of access and less time wasted that appeals to me.
