fujiija Posted December 28, 2015 Report Share Posted December 28, 2015 I am setting up a tank for CRS and CBS. The shrimp will be sent to me in two weeks. It seems everybody uses Salty Shrimp GH+ so I bought it. I also read that the water should be GH about 4, and KH = 0 for CRS and CBS.I added Salty Shrimp GH+ and got to GH 4 as measured by my API test kit. My new TDS meter reads about TDS 65. I figured this makes sense because each degree of GH is 17.9 so 17.9 x 4 = 71, which is close to the 65 that I got on my TDS meter.I looked on some other sites like Discobee and they suggest a TDS of 100-180. How do you get to a TDS of that level when KH = 0? What do I add to my water to get to a TDS that high? I must be missing something here.

fujiija Posted December 28, 2015 Author Report Share Posted December 28, 2015 Thank you! So every person using RO or RO/DI water must be adding something (like Mosura TDS up) in order to take their TDS level up high enough for Caridina shrimp? I read a number of threads about remineralization and I am surprised hardly anybody mentions that the TDS will end up too low at GH 4 and therefore you need to add something else to take it back up to 100-180.

OMG Aquatics Posted December 28, 2015 Report Share Posted December 28, 2015 I get my GH to 6. Ends up around ~140 TDS with SD Bianco ~120 with SS GH+ I add micro nutrients to tank daily so TDS increases slowly daily. Quote Link to comment Share on other sites More sharing options...
fujiija Posted December 28, 2015 Author Report Share Posted December 28, 2015 OK - I think I get it now. Seems that the TDS will depend on what product you add to increase the GH. Salty Shrimp GH+ is "less dirty" compared to other products so it'll take up the GH but the TDS will rise less than if I used other products. I will add more Salty Shrimp GH+ and take my GH up to 6 (currently 4) just to get the TDS up higher. I was not planning on adding anything else to the tank (no fertilizers of any kind) if I can get up to TDS 120 just with Salty Shrimp. If needed, I also have EI fertilizers and can carefully add some micronutrient solution just to get the TDS up a little higher. I realize that evaporation and other organics can also increase TDS over time so I'll be careful. Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted December 28, 2015 Report Share Posted December 28, 2015 Food, wastes, etc will add TDS over time. Quote Link to comment Share on other sites More sharing options...
EricM Posted December 28, 2015 Report Share Posted December 28, 2015 during our Taiwan trip visiting many breeders, one of the questions i was always sure to ask was what the preferred GH for caridina. We've found a majority of them prefer GH3 and approx. 120-140TDS. PRL were usually around 100-120TDS. Quote Link to comment Share on other sites More sharing options...
fujiija Posted December 28, 2015 Author Report Share Posted December 28, 2015 Wow! GH of 3? Lower than I thought. Good to know. Is there any "bible" of shrimp water quality that I should read? Water quality is such an important factor and hard to set up a tank without getting into it. Remineralization was a whole academic exercise in itself and navigating all the brands is something I have barely scratched the surface. Seems all overwhelming at times and I haven't even gotten to the foods! Quote Link to comment Share on other sites More sharing options...

I havent updated parameters in a few months. http://www.discobee.com/blogs/news/17030569-shrimp-water-parameters I try to update them from time to time as we learn more.
