I've used purple up before on my tank for a coraline algae inhibitor, but I stopped until I can get a new test kit for calcium because I believe that it adds calcium to the system. Was wondering if it is used as a buffer at all for calcium? One of the guys at my lfs said he uses it in his tanks as a calcium buffer, but I dont believe that it works that way. Is there any more information about it that you guys have gained from experience? Was thinking about dosing it again on my system. Thanks
