Our recommended choice of filters for nano and standard aquarium tanks that are commonly overlooked. Slim Flo filters by Dymax are great for aquarium tanks up to 20 gallons and are budget friendly. Dymax Slim Flo Filters were designed to be discreet and easy to maintain while providing adjustable gentle flow to cater to an array of aquascape layouts and freshwater fish and shrimp species. Another added benefit for this aquarium filter is its slim profile as the model name suggests, making it great for tight spaces. It’s common practice to run filters that are rated for larger aquarium tanks on smaller tanks for exceptional filtration. These aquarium filters are ideal for shrimp, Betta, and planted aquarium tanks. Additionally, Dymax Slim Flo Filters come with everything you need right out of the box for easy setup and use.
