I'm planning to set up a cycled, 5 gallon tank for a new betta. Sushi's tank was never cycled, so this is a new thing for me, but I have done my research. I'm going to do a fishless cycle with fish food flakes because I can't find any pure ammonia in my area. I'm going to start it up tomorrow.
So, sponge filters.... what's everyone's opinion on this type of filtration?
I'm planning on using a sponge filter attached to a small air pump. It seems like the best, most gentle option for a betta. Honestly, it's about my only option; because I can't use HOB filters due to how my tank is made. I have the Eclipse Corner 5 gallon.
Anyone use sponge filters?
