It's not a little algae. Anymore. No matter what I do how much I remove it comes right back. I have a lot going on right now too. New property, another project car, and well life. When I bought this tank I told myself if I screwed it up again I was out for good. I have five other tanks. So it's not like I'm done done just giving up on salt. I'm going to find my microscope and see what I'm working with here.For a little algae?
