I have an Arctica Titanium Model DBE-200, in-line 1/4 HP. Put it on our 155 gal.three days ago- it's great, and one of the quietest ones I've heard. We had the lfs run it for us before we bought it. Go for it! Dawn.
Don't know much about that brand, but depends on how much light is on your tank, and how hot is the summer, a 1/10hp may be pushing it on a 55 gal... what part of the world are you in? how hot does your tank gets without the chiller? what type of light setup?
