Have you ever/never heard of Fluval products? I rarely see them mentioned on this site. I am particularly interested in their Fluval Flex models. I believe them to be more expensive than most brands but their innovation and workmanship sets them above the others. At least in my opinion. I am also interested in their kits. The 15 gallon model most of all. Information on the 9 gallon would also be appreciated.
Thanks for being here.
I researched the SeaClear Acrylic Aquarium Combo Set a lot and reviews were mostly good. However, after buying this product and setting it up, I have to say that for its price, I was expected a lot more about it. The acrylic is quite clear, much more clear than glass but the LED light is a joke.
I’ve bought a new Tetra 20 Gallon fish tank and it’s better than I expected. The best thing is the filter is quiet and the LED light is amazing!
