Hello brilliant plant minds. I've been doing this for over 20 years and have never had this issue. So I'm stumped. 75 gal medium light co2 injected heavily planted tank. it's been set up for 8yrs, I do weekly 35 gal water change with remineralized r/o water. Gh 80ppm Kh 30ppm. N 20 to 30ppm P 1ppm. No measurable ammonia or nitrite. I have a 20 gallon sump total water volume 80 gallons. It seems every time I clean glass on the tank, sump or overflow box I get a cloudy bloom. Everybody wants crystal clear glass. Plants and fish are loving life but this is super annoying. Has anyone had to deal with this before? I've tried leaving glass alone for 3 weeks and I've tried daily cleaning to no avail. This has been going of for 5 months. Thanks in advance
