Nice. I appreciate the reply. I over engineer everything so I understand. My long term plans are to automate water changes but this is the first step. Forgive me if you already posted it but where did you get the RODI tanks? I like that they're square and fit well with your organization in your garage. Thanks!
Back when I bought them, they had free shipping. Nowadays, it costs more to ship them then the cost of the vessel.
Try a local farm and ranch store or tractor supply store.
If you can’t find them there, try online. If you wish to duplicate my setup, you’re looking for “55 gallon plastic tank”. Google that and you can see if you can one with free shipping.
