swivel Posted March 23, 2016 Report Share Posted March 23, 2016 Hello, Is the TDS is my shrimp suppose to rise as water evaporates? I can't keep a stable TDS. I use RO water to top off my tank. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Mr. F Posted March 23, 2016 Report Share Posted March 23, 2016 TDS will rise as water evaporates because the solids in the water become more concentrated. However you may notice a higher TDS when you top off your water to the original level. This is because TDS will rise over time as a natural part of aquarium processes; solids produced in waste, extra food, etc, dissolve in the water. The best way to keep TDS down is to perform water changes regularly.

DETAquarium Posted March 23, 2016 Report Share Posted March 23, 2016 As Mr. F said, as water evaporates everything that comprises TDS (Minerals, Nutrients, Waste, Organic Matter, Etc.) remain in the water column and/or shrimp tank. This means TDS will slowly rise simply because of evaporation, now in a perfect world if you were to replace that evaporated water with 0 TDS RODI water you would end up with the same TDS prior to evaporation. Unfortunately, TDS will rise even without evaporation simply because of the additional waste shrimp, plants, food, etc will produce. As Mr. F eluded water changes are your friend and even those 0 TDS top-offs will help you bring back your TDS to a comfortable level. The small fluctuations from 120 TDS to a 127 TDS over a week or two's time won't cause any dramatic effects. Just be sure to monitor from time to time and take your time when performing these water changes and top offs.

swivel Posted March 23, 2016 Author Report Share Posted March 23, 2016 Thanks for the great information! I guess I need to stop being lazy and start performing regular water changes. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
