Ben Ellison Posted February 14, 2022 Share Posted February 14, 2022 Do you all combat old tank with water changes only or with things like cuddle fish bone or other additives? I have tanks that are heavily planted and seem to need lots of water changes to combat low pH. Nitrates are all super low so I'm only doing the changes to keep water hardness up. Just curious what you guys all are doing. Link to comment Share on other sites More sharing options...
