Hi everyone! The Wetspot tropical fish has Parosphromenus Nagyi right now, for those American members who are interested 🙂 I am planning on getting a trio next month for a standard 20 liter tank, which brings me to my question…how do you reduce the PH of a licorice gourami tank while keeping the conductivity low? My attempts with tannins have never gotten the PH below the high 5’s, and I don’t want to play with phosphoric acid. Thanks!
