how to increase GH using powder

[ahhian]

Hi people,

I have tried using Seachem cichlid lake salt and Baxter GH-KH Plus but they seems to be insoluble. Anyone has experience using powder to increase GH? What are the brands to recommend?

Just use mosura mineral plus..

I need to increase to about 20 deg for both KH and GH. Can that be achieved?

just keep adding aha..mineral rock will also have the same effect but just slower(over time)..
