I have mostly just chocolate shrimp in that tank along with very few SSS crystal reds.
I also would want that 150TDS but was pretty dumb to use tap water. idk what hit me that day lol!
I do know that my tap water has an obscene amount of phosphates which probably accounts for most of that TDS being above the 150ppm range i am shooting for.
I use mosura mineral plus as my remineralizer.
