Wow, stunning shrimp man!
Have they even given you any problems?
Like most readers of this part of the forum, I've had some issues in the past. Now that my parameters are dialed in, I am having quite a bit of success.
As an example, I killed a bunch of Speedie's shrimp a year and a half ago with Fluval Shrimp stratum and Akadama. Since I switched to using only New Amazonia and Azoo Plant Grower, I have had pretty good success. I also used to mix tap and RO, but found that using 100% RO, remineralized with Salty Shrimp GH+ works better.
I've had even more trouble with Sulawesi tanks. I spent about 2 years keeping Cardinal shrimp in RO water that had been aged for 2 weeks over aragonite sand. My population would wax and wane over time, but it never built up large numbers. (I also had complete failure in tapwater.) In retrospect I think it was partially due to my doing water changes too frequently. Now I'm using Salty Shrimp products to remineralize RO, I'm careful with water changes, and my Cardinal population is doing great.
You should have lots of success if you keep reading this part of the TPT forum, and you'll probably avoid some of the mistakes many of us have made in the past.
