I'm changing all 4 stages of filters this week. (carbon, sediment, membrane, and DI resin) How much water should I run through the unit before I start using the water?

I just got a new RO/DI from Bulk Reef Supply, and they recommended that it was run for 1 hour straight to the drain. The one I had before recommended that you drain it into a bucket until it ran clean (not dark/cloudy) and read 0 TDS. Not really an exact amount since they're all different. I'm sure a few gallons minimum with 0 TDS output and you should be good to go.

you should disinfect it with bleach since you are taking all apart. lots of good info on YouTube on how to do this.
