I am new to aquariums and therefore, new to most of this equipment. I wanted to ask about this before I buy it. I currently have an existing RO system for drinking water and I want to add DI. I am planning to buy this system, along with a T fitting and I will add the T fitting immediately after my current RO, before the RO goes to the drinking water tank. I will then add this, along with a valve, to the T fitting to allow me to keep the drinking water separate from the DI water. Will this system, along with a T fitting work correctly with that configuration? Thanks!

Hi Cory,

The application you describe should work just like our Drinking Water and Reef system. The only thing I would add would be a check valve after the T going to the drinking water tank to prevent that water from being sent through your DI resin when you open that line.

I hope this helps!
Happy Reefing
