Hi everyone! I'd like to start with apistrogrammas in my aquarium, I have a 180L tank. I live in Lima, Peru, but water in my city is very hard. TDS has a reading of 440ppm. Has anyone tried to soften water with chlorhydric acid? I know that I could use a RO system but I prefer to avoid it because of water waste.
