OASE BioMaster Thermo 350

OASE external canister filter in shipping box. Photo by author.

Last month, I posted about the OASE company. I mentioned in that post that I would be receiving a BioMaster Thermo canister filter for review. It arrived!

As you can see in the photo above, OASE sent me the 350.  The 350 is one of three in their external canister line. Designed for 90g tanks, the 350 is the middle size of the three. The 250 is the smallest and designed for 70g tanks. The 600 is the largest of the three and makes a big jump from the 35o, specifically designed for 160g tanks.

Stay tuned!
