maxijazz Posted January 1, 2009 Share Posted January 1, 2009 Just got myself a new toy a TDS meter and my RO water from my filter reads between 1 and 2. At what reading would you change the membrane and or the carbon and micron filter. Thanks Link to comment
The Propagator Posted January 3, 2009 Share Posted January 3, 2009 That's not an easily answered question. Its relative to a lot of different things. You're preference, Algae blooms, Reaction in tank inhabitants. etc etc etc.... Usually its a good idea to go by a pressure gauge as well as the TDS meter. Some times TDS meters showing elevated levels simply mean you need to back flush your system. A pressure gauge will back this up if that's whats going on. If your with out a pressure gauge, 1st try back flushing once you start getting into the 4-5 ppm range. Do this for about 15 minutes. Let it run then re check with your TDS meter. Make sure its calibrated though before reading. Link to comment
