I tried 3 power heads, korilla pico 180, rio 50 & rio 180. The 50 worked best as the shape turns water over and the powerhead arms are able to be angled so slightly.
I made a hob refugium from a medium breeder box, & korilla 50 heater.
Par 38 led-
Had no issues but I had to much rock work to add the corals I wanted, more of a personal preference than anything.
I still have it, going to turn it into a fresh planted frog tank for the little ones.
To small for fish imo-
