Allicat Posted September 19, 2014 Report Share Posted September 19, 2014 The TDS in my tank seems to go down over time. Is that normal? This is happening in my two 29 gallon tanks that house shrimp and around 7 adult mystery snails each and lots of baby snails.

Soothing Shrimp Posted September 19, 2014 Report Share Posted September 19, 2014 Never heard of that. Quote Link to comment Share on other sites More sharing options...
rostick555 Posted September 19, 2014 Report Share Posted September 19, 2014 Mine does too. Mine starts out at 180 after a water change and will go down to 150-160 by the end of the week. I always assumed it was the seachem safe that I dose during water changes and mineral absorption by shrimp and plants. Anyone else have similar experience?

OMG Aquatics Posted September 19, 2014 Report Share Posted September 19, 2014 Never happens to me. I use SS and my TDS stay at around 190-210 Quote Link to comment Share on other sites More sharing options...
Allicat Posted September 19, 2014 Author Report Share Posted September 19, 2014 This is tap water, and I'm keeping neos. I started to add some blue diamond remineralizer when it gets low to bring it back up. My best guess was that it is mineral absorption from my livestock as well. At least I'm not the only one haha.

miwu Posted September 19, 2014 Report Share Posted September 19, 2014 Not sure at all but maybe some kind of precipitation? High concentrations of dissolved salts, pH, etc. might contribute to precipitation but I don't know if it'll actually occur or how much it'll impact TDS.

Mamashack Posted September 19, 2014 Report Share Posted September 19, 2014 Mine usually goes up due to evaporation, but shrimp and plant use sounds feasible I guess. Quote Link to comment Share on other sites More sharing options...
chibikaie Posted September 19, 2014 Report Share Posted September 19, 2014 It's probably all the baby snails. They grow quickly. If you have plants, they will also take up nutrients. What substrate do you have? Some will adsorb ions. Quote Link to comment Share on other sites More sharing options...
Allicat Posted September 19, 2014 Author Report Share Posted September 19, 2014 I do have a lot of Anubis, anachris, and moss. I have Tahitian moon sand (inert) substrate. I'm thinking it's probably the snail babies though, there are at least 20 babies per tank. I sell them as they get bigger so that I'm not overstocked.
