I bought my tank and equiptment used and I dont know what kind of filter this is. It has no markings or anything on it that tells me anything. It has a green sponge that I rinsed out and it now looks new but is still green. I think its supposed to be green
also has a compartment with carbon in it. You can slide the output up or down to make it go fast or slow. I've looked around on like a bit and cant find the exact one.
Thanks for looking
