Rodi

[Coreys reef adventure]

Hey y’all, so I’m having issues with my rodi, I just bought a 4 stage, less than a month ago. Started running it just fine, now I’m here looking at my tds meter ready 3-4, it probably has 200 gallon through it if that, my tds going in is only 60. Please help me.

I have 45-50 psi,

So 60 in, 3-4 out of the membrane?

That sounds like a 95% reject, so it's not that abnormal.

What were you getting earlier that has your concerned?

Run the unit for 10 minutes. What are your Tap and post RO TDs readings? tap water temperature? Pressure gauge reading? and what are the flow rates in ML/MIN?
