polarbear Posted June 19, 2011 Share Posted June 19, 2011 Will 001 ppm of TDS hurt my tank? The reason I'm asking is because I was making some RO water earlier and noticed that the TDS meter was showing 001 on the output meter. I have some new DI resin that I'm going to switch out tomorrow but may need some RO water in the mean time. So back to the question, will 001 ppm of TDS hurt my tank if I use it for topping of the refugium? Quote Link to comment Share on other sites More sharing options...
Timfish Posted June 19, 2011 Share Posted June 19, 2011 I would say no problem at all. Quote Link to comment Share on other sites More sharing options...

+KimP Posted June 20, 2011 Share Posted June 20, 2011 Ha! I wouldn't have even blinked an eye at .001, I think you'll be just fine Quote Link to comment Share on other sites More sharing options...
ramsey Posted June 20, 2011 Share Posted June 20, 2011 I personally replace stuff anywhere from 5-10 PPM. You're good with 1 PPM. Quote Link to comment Share on other sites More sharing options...
