All we get on this forum is this great connection between GH, KH and pH. I will say it on this thread as well. If you get your tank producing enough acid your pH will drop. If you use a peat base in your tank and do 25% water changes instead or the site preferred 50-75% water changes your pH will drop. No two tanks are alike, the amount of water you change will vary from system to system depending on what you want to keep. But there is a way to successfully keep a variety of different fish, fed from the same water source.
