thanks! I was just looking for a detailed review of them and how they worked compared to my cheap walmart filter
Yeah my Walmart version doesnt have the biowheel. Are "cartridges" like the blue ones in my filter now? If so, can't I just use the ones that are made for that filter?
No, it wouldnt be too much flow.
Although, I believe these bio-wheel filters are overrated. If I were you, I would buy 1 of those penguin 350 filters and 2 or 3 sponge filters.
These sponge filters are amazing; I use them in all of my tanks.

Dont forget, you'll need an air pump!
Also, to cut down on cost at the beginning, could I get away with just using 1 Penguin Bio Whell 350 and add the other one later, or should I put them both on at once?
