Mishiri Posted January 31, 2018 Report Share Posted January 31, 2018 I have some PRL CRS, and currently my TDS is around 155-160. If I use RO water to do my water change, and add some Salty shrimp remineralizer to it to bring the GH to 5... that would be around 70-90 ish TDS. If I used 90 TDS water, would that big of a difference in TDS harm the shrimp? Or should I gradually lower the TDS over time such as: Using new water around 130, then next water change 120, etc etc? Thanks Quote Link to comment Share on other sites More sharing options...
