I had an algae bloom and was thinking possibly my RODI water was causing it. I bought an in-line meter and my TDS readings were 295. I thought the TDS numbers should be lower than that. I just replaced all of my filters in it and my readings are still 225 I’m flushing it out to see if maybe that’s related to water in the lines but what should my numbers be? If they don’t go lower what should my next move be?
