Rycraft Posted January 2, 2021 Share Posted January 2, 2021 So my tank KH is 3 (tap is generally around 5) and I'm looking to buffer the KH a bit for my live bearers. Water changes don't seem to be able to increase it and I don't want to do large water changes all the time. I have media bags and aragonite. Am I better off putting the media bags below my imagitarium black sand substrate or putting some in a smaller media bag in my filter? I don't want to litter the substrate with it because I want my Corys to be able to happily sift through the sand. I just didn't know if it would still buffer the KH if it's buried under the sand. Any advise would be appreciated. Thanks! Link to comment Share on other sites More sharing options...
