Sponge Filter Question

[Chiclid addict]

So my 55s filter is on the brink of death and I want to put sponge filters in and I want to use coops but larges are out of stock and I was wondering if 4 mediums would do since it’s the same volume as 2 larges and I can’t really wait for them to come into stock since the filter is about to die

You can actually stack them, do you can put 2 mediums together to form an ultrasponge! However, you could probably get away with w mediums, they are pretty good sized.

@Goosedub is on point. 

Dont forget, alot of for BB is in the tank. On the walls, on the substrate, the decor. 

@Cory mentioned a while ago he prefers the medium size over the large as they are easier to squeeze when you have to do 50 at a time. If you go with 4 mediums, you could do 2 at a time and alternate bi-weekly. The setup may be a little bit louder overall, but hey, probably still quieter than a HOB.

The Co-Op only carries the large because people wanted it. They recommend medium. I did not know this and bought two large. I REALLY wish I had selected the mediums. One of these days I’ll replace them. Maybe sooner rather than later.

In my opinion, I would go for two Medium Aquarium Co-Op Sponge Filters if I were you. However, your stocking levels do come into play on how much filtration you need. If you don’t have a heavy bioload, two Medium Sponge Filters attached to the Aquarium Co-Op USB Nano Air Pumps will handle the tank perfectly.

My stocking is 3 discus, 1 angelfish, 1 pleco and 1 rope fish how many should I run
