I currently have a 40 breeder softy and LPS reef. The size is perfect for me. I prefer a KISS style system. But In all my years in the hobby, I’ve been fearful of sumps and have always used hang-on equipment. I am considering upgrading systems. Either an all in one or possibly a super easy to put together sump system that is pretty much guaranteed not to flood - is there such a thing? i need to stay with a 36” tank. My goal is to have low iron / star fire glass, surface skimming, an auto top off and EASE of maintenance. What is easier?? AIO or sump?? I've looked heavily at Waterbox. Just started looking at Red Sea. Are there any other systems I should be looking at? Thanks!
