Means you have low KH and medium-high GH.
From my own personal experience, I'd recommend using RO water or distilled with a shrimp remineralizer. Go with some cheap crystals or tiger species. Choose a breeder (not import seller) that you want to purchase from and match their parameters. If they are raising in low pH, then you can use Controsoil and a GH only remineralizer. GH is likely going to be around 3-6. If in higher pH, then you'll want inert substrate with GH/KH remineralizer which might be remineralized to 6 GH and 3 KH or higher.
I would not recommend Neos unless you can find a local breeder who raises them in same water... even then, would not recommend putting them in community tank. Only amanos if you do want to try any type of shrimp in there. Shrimp would do best in their own tank.
Since there is KH in your water, you are causing parameter swings each time you do a water change on your community tank. Shrimp do not like this, but amanos (and fish) could probably handle it. Having low KH helps. The problem is is that the soil is absorbing the KH and releasing tannins, fulvic and humic acid into the water to lower the pH. KH wants to raise the pH, so each water change means a fluctuation in water parameters.
