I bought the BRS 4 stage plus ro/di unit a few months ago during the summer when I initially set up my tank. (red sea reefer 170) https://www.bulkreefsupply.com/4-stage-75gpd-plus-ro-di-system-bulk-reef-supply.html
It was working great until recently the TDS meter started reading higher out TDS than in!
In is about 25 ppm where as the output is about 35.
I run it at about 60 PSI off soft water.
I probably make about 12 gallons of water a week with it.
Flush kit isn't making any difference. And I haven't fiddled around with the connections for the TDS meter or water lines.
I doubt I've exhausted the resin or membranes this fast, Any ideas?
