Simply Koi and More Koi

Thanks

thanks for your answers, is there a kit or something that I can use to measure the KH of my pond or do I measure the PH and go by that? sorry for the basic questions but I've never heard of KH before and I run a bubble bead filter on by pond.

Thanks

Mike

Hi

Please excuse my ignorance but what does KH stand for, and how does one change it? either lower or higher.

Thanks

Mike
