That is a big question Welcome to R2R Some of the Main stuff I have
Apex Gold

Wow.
There are as many ways to run a tank as there are ways to bake cookies I think
I run an apex controller, T5 lights, ozone, and dose kalk, mag, vodka (in process of switching to vinegar), and for the next week or so, Lanthanium Chloride. Probably start dosing nitrates by end of month.
I also run a couple of airstones in my sump, and am considering adding a couple of gallons of bioballs again......also thinking about a diy algae scrubber for the sake of experimenting.
