Choosing RO/DI Unit for Aquariums and Drinking Water

[gregzz4]

I can't add to my last post, so ....

Choosing a storage container for your RO will depend on how much you think you will use
My drum holds about 45g, give or take, and I have to run my RO system a couple times a week or so, depending on what I'm doing

I have a DT with a total of 110g of water, and currently am running a QT with 20g

I go through about 11g/week due to evaporation, 20-30g/week for water changes, and another 10+g/per week for rinsing stuff
So, I run my RO whenever my drum is below half full

You will have to decide how much water you can store, how much you will use, and how often you will run your RO or RO/DI system

Hope this helps
