Company Rena [FONT="]Model[/FONT] Filstar I1 Mini [FONT="]Link to product description [/FONT] http://www.aquamania.co.uk/product.asp?numRecordPosition=1&P_ID=1623&strPageHistory=&strKeywords=&SearchFor=&PT_ID=236 [FONT="]Price range[/FONT] [FONT="]Pros[/FONT] VERY powerful filtration and is very compact, making it good for small tanks. Easy to take apart and clean. Cotains a compartment for a "Rena crystal" or chemical filtration of your choice. [FONT="]Cons[/FONT] I have found that the suckers that hold it to the glass aren't very good. Clogs easily if there is a lot of suspended particles. Cannot be kept to close to the surface or it fills up with air and the tank becomes a mass of bubbles. [FONT="]Star rating (1-5 with 5 being the best)[/FONT] 4 [FONT="]How long have you used the product?[/FONT] 5 Months approx. [FONT="]Build quality and value for your money. [/FONT] Build qualty is good and it is very difficult for anything to go wrong with it. Great value for money. [FONT="]Other comments[/FONT] This filter comes with many small aquariums that have rena products included. I have used the propeller when i made my own external filter and as a co2 diffuser and it is fine through whattever it is put through. Very good filter for smaler tanks; I would deffinately recommend it, although one may need to find ther own suckers as the ones included arent great. Thanks for reading!
