Query: AMAZING FILTER

This filter is truly amazing. This is my second filter that I've bought only to add it to my new 75 gallon tank. It worked amazingly in my 29 gallon tall. My water was always crystal clear as long as i did my normal weekly water changes. I love that you can customise how you want to filter your water. I personally do a sponge on bottom, bio media in middle and another sponge on top. I have not yet replaced any of the supplies that they give you because I dont believe they need to be replaced at their reccomended time frame. My aquarium is always crytal clear and my fish love it too. Great filter. Would reccomend to anyone for H.O.B. filter.
