I've heard from other members, that have used this, that its not really worth it. The gph appears to be no more than that of the CFS700, and maintenance is a PITA due to the height. However, you can definitely put a lot of bio media in that beast.The CFS14i looks pretty dope too
If you plan to give these canisters a try, there's acouple of things to be aware of. 1) the O-rings that allows the hoses to be disconnected from the body is a bit too large, and will make removal a Herculean effort. There's a proper sized O-rings (which I can track down if you want to know). There water shut off connectors tends to leak after a couple of years, due the custom O-rings wearing down over time. However, these connectors can be replaced for only about $10. Also, don't over tighten the lid screws, there's no need to. People complained about cracked lids, but I have 4 of these units for more than 3 years, and have no cracked lids.
Besides, these 2 issues, these canisters are workhorses and the CFS500 and CFS700 have really powerful pumps
