PH/KH too high?
I just re-tested my tank and my PH is 7.8. My GH is at 120 ppm while my KH is close to 300. I understand (basically) the relationship between the 3. I understand that I have water on the "soft"er side. My concern is that my PH may be a little too high for the fish I currently have (neon tetras, cory's, danio's, guppies, raphael catfish). Ammonia/nitrite/nitrate levels are fine.
Should any of these numbers alarm me? If so, what is the best way to reduce them? I understand there are chemicals to artificially lower PH but, as with just about everything, I'm sure a more natural solution exists and has less chance of harming the eco-system.
