SRC Member ml708 Posted February 10, 2014 SRC Member Share Posted February 10, 2014 I have a high TDS reading from the water I have added in a few of my tanks, both fresh and saltwater. Have been doing partial water changes of 20% every 3 days but I'm afraid that the TDS in the tank is not going down fast enough. Any idea of any chemical I can add to speed up the process?

SRC Member ml708 Posted February 10, 2014 Author SRC Member Share Posted February 10, 2014 yes unfortunately because my DI unit was not working well and I never realised it, until I tested and saw water coming out at 64. My tap water is 67. so I got a new RO/DI unit which is giving me a reading of 0. Quote Link to comment Share on other sites More sharing options...
SRC Member Aquareef123 Posted February 11, 2014 SRC Member Share Posted February 11, 2014 Slowly overtime with the new RO/DI changing water, your nutrient will start dropping. Quote Link to comment Share on other sites More sharing options...
SRC Member ml708 Posted February 11, 2014 Author SRC Member Share Posted February 11, 2014 Does TDS also lower on its own as well if no new nutrients are added to the tank? Quote Link to comment Share on other sites More sharing options...
SRC Member Aquareef123 Posted February 11, 2014 SRC Member Share Posted February 11, 2014 Yes. Some of the nutrients will be consumed by the corals but not heavy metals. These heavy metals need to be get rid of through water change using RO/DI water. Quote Link to comment Share on other sites More sharing options...
