Is there anyone out there that has used this filter and can answer a question I have about it? It has to do with assembly.
it's just a simple air driven sponge filter. My question has to do with the diffusion chamber on this particular model. There's 3 holes that I need to know if they need to be open or closed. I have them open at the moment. Do you know of this that I speak of?I've assembled a bunch of similar ones before, does this one come with a filter or is it just the sponge?
