So im new to this and will be building a 20g long sump with a refugiam as i'm really interested in having macros, and more importantly a manderin goby. I dont know anything about sumps besides the refugiam part and im having a difficult time finding any info on what needs to be included, how many chambers and what each chamber does. I know i need some baffles, return pump, and maybe some filter socks, but how many chambers and how big? why are there really tightly placed baffles on some sumps? Im assuming the chamber size and baffle position is important? what about a bubble stopper? What do the other chambers do and what should they have in them? to me it just seems like they all hold water, and thats it
