Remineralize?

[OakenGoby]

I recently watched Cory’s video on TDS meters.  One thing that I found very interesting was the discussion about neocaridina shrimp and low TDS. My reading has led me to believe that neocaridina need a TDS of 150-250 (based on RO/DI, distilled, or rain water remineralized with a GH/KH remineralizer such as Salty Shrimp GH/KH). Cory tested two neocaridina tanks and both were under 70 TDS (one was in the 60s and the other was in the 20s I think).  Shrimp were thriving and breeding. My tap water is naturally soft and low tds (around 20-26 consistently). I currently remineralize RO/DI water with Salty Shrimp for all of my tanks except my shelldwellers. They get Seachem Lake Tanganyikan minerals. The more I think about it, the more I think this might not be necessary (except for the shelldwellers). Here’s a test strip of both RO/DI and tap - nearly identical. This is my baseline. I wonder if adding crushed coral or wonder shell would be a better (read “easier”) solution or if that is even worth doing.  I also find that I put off water changes if I first have to make water and remineralize it.

What does everyone else do?

I would use the salty shrimp GH/KH and just use your TDS meter to reach the desired TDS.
