Need advice on substrate for new planted shrimp tank
I am wrapping up my first 10.8 gallon planted tank housing tiger and tangerine tiger shrimp. pH 6.7, GH of 6, KH of 0, TDS about 200 (wanted a little lower), Temp 74 degrees. I used Fluval Shrimp Stratum for my substrate.
I am ready to start my second tank (low-tech). It is a 16.1 gallon tank (15.6 in x 15.6 x 15.6). It will house Red Cherry Shrimp. So I am looking for about a pH of 7.4, GH of 8, KH of 4 and TDS of about 200-225 (other suggestions are welcomed). I will be using RO/DI water mineralized with Salty Shrimp GH/KH+. My big question is what substrate to use - I was looking for something neutral that doesn't buffer the water either way. Also looking for a darker substrate.
At first I was leaning toward Eco Complete (black). But then read articles on it raising KH and pH. This would be ok if it kept the pH around 7.5 but I don't want it above 8.0+. If the effect is temporary (month or so, then OK).
Question: Which are some good (neutral) substrate choices for a low-tech planted with Neocaridina (ie Red Cherry) shrimp? I definitely don't want to use Fluval or any substrate that buffers to the acidic side. Also looking for a substrate that is good for plants. Thanks!.

Reason: Make note that new tank is to be low-tech
