Not sure what you mean by 'filling up after a wc directly....'? Filling up what? Your tank or sump? I have a separate container to mix up my water for water changes. Always fill that, add salt & mix for at least a couple of days before doing water change. Water changes for me involve siphoning the display & then bucket brigading 23 gallons of fresh salt water up from the basement. Good workout.

My sumpless 77 gallon Hagen evaporates about a gallon of water per day, so I use glass wine carboys that hold approx. 6 gallons of fresh RODI water as automatic top up directly into my display. A small air pump on a timer keeps the carboy pressurized & the water gets pushed to the display through a mechanical float valve. Takes about 2 hours to fill one of the carboys. Production rate is highly dependent on water pressure & temperature, so don't necessarily expect to get the advertised gpd from your unit.

Mike, sorry for the confusion, i also have a fw tank. I was thinking of just filling up that tank after a wc directly from the ro unit, saving a step.

I mix mu sw in a 6 gallon bucket for 24 hours with its own circulation pump.

You're still gonna have to remineralize the RO water for you freshwater tank. You can use additives or mix with aged tap water.

Is using ro for freshwater a bad thing then? Should i just stick to conditioned tap water? I know Calgary's water is quite good, i let mine sit out for 24 hours in two 5 gallon pails before using plus use water conditioner.

I use my waste water from my RODI for my fresh water tank. I find that a higher mineral content in my water makes my FW plants strive.

I don't recommend RODI water for a fresh water planted tank unless you add supplements.

Good to know, thx. Do u still have to use Prime on your waste water or is all of the chlorine gone in waste water?

The carbon filter plumbed in before your RO membrane takes care of chlorine. Without it, your costly RO membrane wouldn't last very long. So yes, all the chlorine should be gone in your waste water, no need to treat with Prime.
