H2o question

Anyone on here I've seen talk about changing their DI always mentioned when it reads anything but 0, although some push it to 1 or 2.
If you're only getting 0.02 from your RO, IMO, you're fine.
I'd keep the DI operational for those times, like after a storm or such, when the TDS spikes and your RO just isn't enough. Then you can still drink it.
If it ever does spike, run the DI into a separate container for fish only, and you can still drink the RO.
