Hi, I'm setting up a cherry shrimp tank for the first time and it seems like a lot of shrimp breeders recommend dual sponge filters. I can see the advantages of the dual sponge filters being that they are easier to clean (popping out one sponge is far easier than a barrel one), you can remove one to cycle another tank, and they don't take up any space on the tank floor.
Are there disadvantages over a single barrel one apart from a little less suction power?
I've watched many of Cory's youtube videos and I haven't seen one where he talks about dual sponge filters. Does anyone know why he doesn't carry them?
