Im looking for another tank for my Betta. I was looking at couple today and one had like a 3 stage filter, it went through the sponge, through a carbon bit then through a bit with pellet like things in it.
I was wondering if there is much advantage of having a filter like this other than one with just a sponge?
Appologies if this is a poor description but hopefully you know what i mean!?
Thanks alot
