From what I remember reading , a pH swing of .5 is not a big deal . But at what kH level would I need to be at the .5 swing (60 , 80 , 120) ? I'm lucky I guess with my kH or maybe it has something to do with proper filtering , water changes & stocking levels of koi .
I know of some mad scientist who have raised their kH up to 600+ using BS (Why I don't know , sence we all know it doesn't need to be anywhere near that level) . Hopefully they don't have a basement full of puppies & monkeys as well .
