Cheap filter for quarantine tank

  • We are currently upgrading MFK. thanks! -neo
The only reason these filters aren't the norm is that they are generally considered ugly. I have my sponge hidden behind a fake mangrove root, so you can't really see it. I have also used a power head to increase flow-which kinda backfired when using in a tank that has a sand substrate...When i rinsed it off, I got mud...Darn digging Plecos..haha


And yes-sponge+air line+cheap air pump= benificial bacterial and no moving parts...Great for fry tanks too!
 
you can make your own diy sponge filter with some pvc piping and some sponges its pretty easy but then again sponge filters are relatively cheap so its your call
