RO water

[Noob1234]

Hi guys
Not much of a poster but I do have one question and I think the answer is pretty obvious but I do need help in fixing it.
Just bought a RO unit and tested the output at 2 ppm, great, filled my TO tank up and now measuring 150? Obviously I need to clean my TO tank but how? Just empty then clean down with kitchen paper? Seems very high to me but I have never tested RO water before so is this normal?

thanks in advance

Are you using RODI or just RO? If you're using a DI filter at the end, your output should be 0 TDS.
Yes, an uncleaned container can cause you to get TDS readings. I would rinse it out with your water and wipe it down with some paper towel.
