Matt, sera makes wonderful bio media. One of the best in the market. SeraSiporax. Tried and true I’ve used it in most of my tank. As far as filtration goes. I’d rather get a FX-6. Never used their filter but I’ve seen and examined it in person. Plastic feels cheap, has a lot of bells and whistles, but you know, the more they add is cover up what they lackGood to know. I might go for this filter on the means that I have an opportunity to get it for much cheaper than an fx6. Some of the products I have used so far of theirs have been good.
