Help with water changes, ATO and patience :)

If you watch your Tds out if the ro membrane you'll notice on startup there is a large spike before it hits it's stride. This is Tds creep and I use a valve to divert ro water straight down the drain until it subsides then allow it into the di resin. Not doing this and also allowing the unit to turn off and on itself without bleeding this Tds off will exhaust your resin much faster.
