Two Little Fishies just released the Phosban 550, a larger version of the best-selling 150 model. While the 150 certainly received rave reviews from customers, it was only designed for aquariums up to 150 gallons. Not sure why TLF opted for the 550 handle, but the new model actually accommodates tanks up to 600 gallons.
Set one up with phosban as a phosphate remover or utilize one of the many different carbon medias we offer. A pump is not included (hey, it’s only $62.99, what’d you expect?), however, since the 550 is outfitted with ½ inch fittings, you’ll be able to choose from a wide variety to feed this monster.
The 550 includes a ball valve to keep the flow in the 100-200 gallon per hour range. You can fix a maximum of 750 grams of phosban media in the reaction chamber as long as it is under the 8 inch media height restriction within the chamber. Two Little Fishies Phosban Reactor 550 includes a tank hanger for hang-on back (HOB) applications, although you can also install it in-line, in-sump or above the tank as well.
