It has some flaws for reef applications but is good for a small quarantine or fish only tank. Liked about it Nearly indestructable and I have one over 5 years old. Offers mechanical, chemical and biological filtration togethor. Didn't like Too many separate pieces and the biowheel needs bearings to run properly. It can create nitrate issue in a reeftank. If clogged water will bypass carbon, Overall rating:   3.5 Overall satisfaction:   3.0 Would consider buying it again:   4.0 By jenglish Apr 26, 2009   Ask jenglish a question about this item.
