[FONT="]Company[/FONT][FONT="] Hagen Model Aquaclear Link to product description http://www.hagen.com/usa/aquatic/sub_category_psubtype.cfm?CAT=1&SUBCAT=107&PSUBCAT=10701 Price range $27-90 Aquaclear 20-110 Pros In my mind the best hob out there. The way it’s designed gives you limitless options for filter media. As long as you take care of the filter clean it monthly it never breaks down. It also runs silent. If you keep the water level up you will not even know its on. Cons I really can’t think of a con other than the price has shot up a lot but still good value. Sand, snails or other things can cause a gridding sound but if you take it apart and clean it out it will be fine. Star rating (1-5 with 5 being the best) ***** How long have you used the product? 9+ years Build quality and value for your money. I have yet to have one break down on me. Other comments [/FONT] I won’t use any other hob out there. Remember with any filter they over rate them. I tend to cut in half the recommended tank size they say. For example on a 20 gallon tank I use 2 aquaclear 20’s or a aquaclear 50.
