inTank aquarium-specific designed Media Baskets help improve the filtration and clarity of your aquarium while making maintenance extremely easy. What once was a dreaded chore of chaining filters and diving into the aquarium is now made easy utilizing a 2-Sided Tower Design system. The stock Fluval filtration is very dirty, an inTank filter system will fix flow issues with the stock design and sustain the aquarium longer.
