How do i create RCS breeding parameters with high pH, kH and GH source water?

Water parameters from my tap:

kH: 7 (125ppm)
GH: 11 (196ppm)

I'm trying to follow the information given on But it doesn't really provide info for high pH source. I would not want to be using RO or distilled water.

Is aquasoil such as UP aqua shrimp sand a good choice? Says it buffers to 6.5pH, does that mean it will lower the pH/kH from my source?

I should grab a bunch on indian almond leaves?

Should that be enough? what else can I do?

RCS don't need the low ph that many other shrimp do.

I've not tested in a while, but my tap water this summer was something like

Ph 8.2
Gh 16
Kh 8

After letting the water set out for a day, the ph had dropped to 7.8.

RCS are breeding in it. They are in a heavily planted refugium with oak leaves, but the oak leaves do not change the ph at the level I use.

We have extremely hard water here in Houston Texas.
Ph - 8.4 TDS - 300-400 ppm
Red Cherry Shrimp (RCS) breed like roaches with only a dechlorinator added to the water. Many tanks are planted, but they only receive Seachem ferts. Sulawesi and most neo's do great in harder water. Your issue would be in softer water species (CRS, Tigers, Bee) and for that I would recommend RO/Distilled water added to tap to maintain whatever parameters you desire. Ph reducing substrates can assist in this regard as well.
