Can you buy this type of filter for home tanks?
What is this filter called that seems to be in most store tanks that I've seen in videos? It's at 4:10 min in this video and many other times in most of the store tanks. It's a sponge that often seems to have plant matter growing from the sponge that the fish eat. https://youtu.be/cJKQLnAaDlc How come I've never seen a filter like that, which also has air bubbles coming from it being sold for home fish tanks? I was told I had to buy a filter and air pump separately.

OK thank you. That was what I wanted to buy. I asked them in the store if I could buy a filter and air pump together, to save noise of two machines going, but they only gave me the option to buy separately. I suppose so they could make more money.
