Lowering GH/KH: Do I need to treat rainwater before using?
I've recently set up a 5.5 gallon aquarium, currently low tech planted but unstocked. My water here is VERY hard. Using the API test kit my GH is 200ppm (11 drops) and my KH is 400ppm (22 drops). I am wanting to breed cherry shrimp and know I need to adjust my parameters a bit before getting them. I'm thinking of using rain water. Do I need to do anything to it before using it such as use Prime, etc? Other than using RO water or rain water, what are my other options for lowering GH and KH?
Edit: my Ph is also high (8.4) so I'm hoping it will help with this also.
