It’s funny how everyone says it differently. The correct pronunciation is “oh-ah-zay wiith Eoropean flare…….lol. I just recently set up the Biomaster 350 Thermo on a 45 gallon long Mbuna Cichlid tank. The tank is in my living room so I wanted something quiet. My previous tank had a HOB and it made a power hum sound that drove me nuts. Tried a few different brands over the years and it was always the same thing. The new Oase is silent. I love it…….I didn’t use the Hel-X that was packaged with it as I wanted to use my already seeded Seachem Matrix. That is working out well. The easy access prefilter is a great idea. The filter can be kept cleaner of flow killing gunk and will need to be broken down less.

How load is this filter ??

Is it enough for a 130 liter tank?
