I recently setup a coralife RO unit and have a TDS reading of 25. Is this water too bad to use for water changes? I know ideally I want it to be 0, but is 25 really too high. I only ask because I know I will be puttin it in the tank which is full of fish poop, sand, mud, etc....... and I wonder if having a TDS of 25 is really going to be a major bad thing. My TDS from the tap is 324. The unit has only made about 100 gallons, and initially the TDS was 15 and it has now gone to about 25. What are your thoughts???
