Hey guys, I just set up my 75g tank. Need some advice as this is my first “real” tank(other is a 3.5g betta tank). I am a total amature to tanks like this. How does the decor look? Thinking to cycle fish less with stability. I want a mostly peacock tank with few haps sprinkles in. How many? How many Plecos/cats? Do I need bubbler or can I use power head to break surface and bring oxygen. Should I use nitrate remover in filter after cycled?which one?
