I actually went with a fusion 20, they both have the same filtration system. I’ve had mine a bit over a year and it has been really easy to maintain. I am running the original pump but have replaced the filter socks with filter sponges, easier to clean and better flow by using them. I have the desktop ghostskimmer and a fluval 306 running as a media reactor with matrix, carbon and purigen. For lighting am using 2 ai primes hd 8” awl. Parameters have always been stable i would say almost like an ulns.
