I have a 200 gallon and a 125 gallon, been running API nexx filters on them and the water stays cloudy/murky I want to build a sump but have idea on the hole sizes, pump size or sump size I'd need to make it work properly and not have a giant mess on my hands, also I'm interested in a fluidized bed with k-1 but again don't really know where to start, so If anyone has some knowledge on this or some plans please help me out thanks, O my tank as of now has South American Cichlids in it, but wanna get my filtration down so I can get more advanced species like stingrays and maybe start a reef tank in the future
Thanks,
Derik
