APT Zero (1) - The best all around fertilizer!
I have been using APT Zero (1) in my tank for well over a year, after starting it off with APT Complete (3). It's super easy to use, either by dosing it yourself or by using a dosing pump. You only need this one fertilizer and maybe the occasional root tab, like APT Jazz. My tank is 2.5 years old, and I am super happy with it!
