I have a problem developing in my 55 g freshwater community tank. I have glacial runoff well water, very hard, ph 8.8. The fish I have are fine and happy. HOWEVER I'm getting the hard mineral buildup on the sides. I need to get it scraped off without messing up the Zen.
Tank's glass, and it will barely scrape with even a putty knife. I've tried hauling city water and mixing it in, but it doesn't help.
Suggestions?
