Hi everyone,

The CRS in my tank are not breeding, and I think this is due to the GH and/or KH of the water. I don't know the parameters of my tank, because I've never had issues with the health of my Sakuras, and they breed super easily anyway.

Can anyone recommend me good brands of test kit (GH and KH, pH would be a bonus as well), and as a related question, any brands of buffer as well?

I would prefer not to spend too much money on kits/buffers, although a good brand is definitely important. For example, I use Seachem for all my fertilisers.

Any advice would be appreciated!
