H2o question
 

Hi all, just setup my new reef and i'm curious what folks are using for water.
I have an RO/DI but for the last 4 yrs i have been running it strictly for RO drinking water, I filled the tank with RO at 0.02 ppm tds and I hope that's good enough? Or do i need to go back to DI for the tank water???

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.
