HI guys, I am planning to build a large aquarium in near future ,(my previous one being 10 gallon). my tap water have a slight brown tint. So I am using packaged drinking water for the current aquarium. I want the new tank water to be pristine without changing 50% water every week. As it is going to cost a lot. What do you suggest? I want it to be crystal clear water not even a slight milky tint. A lot of youtube videos who says how they maintain clear water actually have a slight whitish water.
