Before I could make hundreds of gallons with no worries no I am fighting filter replacement regularly to keep outcoming TDS between 0-3. I just replaced my sediment filter recently and have made maybe 200 gallonsand noticed yesterday it already looks discolored and TDS out is at 3....count your blessings at 30-40 in
