yes the 301 had to look at my ebay page lol. My tank is 30 gallons with about 10-12 in the sump. Works flawless.I have the same knock off. Its the sca-301. I got mine off a user here used for $70 shipped. Best $70 spent on my tank thus far. I have a 33L with 20L sump, roughly 40G total volume. Works awesome.
