Aqua Safe Question

[fkshiu]

The final carbon filter is for taste because DI water tastes like crap. It does add stuff back into the water.

Keep it if you're using the unit for drinking water as well by teeing off the water between the RO and DI stages. One side of the tee goes into the final carbon filter for drinking, the other side goes into your DI for you aquarium water.

If you are NOT using the Aquasafe for drinking water, chuck it.
