Humic Acid / Blackwater extract?
ive never baught that blackwater stuff and proberly never will. but i know people use it for tanning the water for tetras and such.. so my question is does it just contain humic acids? you can get pottasium humate and i wondered if it would be a good suppliment for breeding?
could it have the same effect as peat and possibly some bogwoods?
i doubt this stuff would stain the water, but then again i dont know what colour the powder is but it is extracted from soil
