Sponge filters

[YellowRose]

I was wanting to set up a second sponge filter in my 36 gallon bowfront. I've heard of two ways to do this. One way is to use a splitter and the other way is just to stack the filters together. What's the difference and is one better than the other?

I have one pump....

could be done either way. running them separate would be desireable if you wanted circulation from it in another part of the tank. if you just want more filtration, stack em.

Is one better than the other? Probably not. I'd go with two separate ones personally, simply because they'd be easier to manage. I could clean one at a time that way and disturb the biofiltration the least. Either way works though.

Make sure your pump has enough output if you split. I sometimes have to use a higher output pump when I use a splitter or I get no bubbles on one or both

I have done both; I'd say the benefit to having two separate is adding additional water flow to another area of the tank via another sponge. In the tanks where I only have one sponge, or stacked sponges, I still added an air stone to the other side of the tank for flow.
