mineralized topsiol for softwater tank?
i am excited to try the mts substrate method, but have one question that i have not found an answer to in all the threads i've been reading.
i noticed that for the diana walstad method, the Gh and Kh of a tank need to be in the middle range for success.
i am working on tanks for killifish, which want to be in really soft water. does soft water ( Kh 2, Gh 3-4) in any way impact the efficacy or safety of using MTS substrate.
