Water Parameter Okay for Neos?

My tap water parameters read ~
PH: 8.2 (reduces to 7.6 after a few days of sitting out)
GH: 1
KH: 1

I've heard two sides of whether PH or GH is the cause of shrimp death so I'm just looking for some clarification. If I increase GH to ~5-6 and keep this stable between water changes will that be okay to keep Neos? I don't plan on changing KH, unless this is recommended. Any input would help!

6-8 GH and 3-4 KH is recommended. Right now, it sounds like both are 0 (0 and 1 read the same)

So right now, no, your water is not suitable for shrimp. There's not enough minerals in the water for the shrimp to be able to molt properly.

Can you double check those test results before we go further? That's an awfully high pH reading for a 1 KH.

Nothing good happens fast in an ecosystem.

So I tested my tap water again and it seems it's closer to 2 KH and 2 GH. I was told that if i leave my water to age, the PH should drop from 8.2 to ~7.4. Now another question I have is if I use acid buffer and alkalinity buffer when the water first comes out of the tap (no aging) to achieve a 7-7.2 PH, and then wait a week will my PH be even lower than 7-7.2 due to aeration and gas exchange?

Maybe.... but you are playing with fire. Adding anything like acid buffer or alkalinity to chase after an "ideal" pH is going to cause more harm than good... and your water still wont be suitable for shrimp.

I once used an acid buffer... on water that typically comes out of tap around 7.2 to 7.4 maybe? And yes, it did initially lower the pH... the following day? It was above 8 pH if I remember right! So IMO, not worth the hassle as well as change in TDS/osmotic pressure that it causes.

Easier to raise your KH and GH and not worry about the PH IMHO. Atleast GH anyways is as simple as adding equilibrium or niloc Gs stuff or one of the others. NilocG stuff mixes better IMHO. Do this in a barrel or whatever container is adequate for the water changes a couple/few days ahead of time.

Wanted to add my weird water here in the PNW from our well comes out of the tap at about 4-5KH, 1GH, 6PH. After degas its 4-5KH, 1GH, 8PH. I add equilibrium or more recently the niloc stuff to raise GH to about 6. NEOs do pretty good along with the false amanos and other fish. I do prep water on Monday or Tuesday (including putting heater in so temp is +/-2F of tanks) for water change Thursday. Do water changes every week about 50%. Have bunch of fish and plants and what not so kind of have to.

I'm going to set a side a couple of gallons ahead of time and concentrate on proper KH and GH and worry less about P. Adding in all the all these extra things to lock in on PH raises TDS to levels I'm not comfortable with, even though it's within acceptable range, it's not optimal.

Thanks you all for the help here!
