Basic 4-Shelf Media Basket for Fluval EVO 13.5G / 16G – Fix Inefficient Filtration, Eliminate Bypass, and Customize Your Setup

Struggling with cloudy water, leftover debris, or inconsistent water parameters in your Fluval EVO?

It's a must-have upgrade for anyone looking to improve tank health with minimal effort. 💧 **What It Does Best:** * Stops inefficient flow by eliminating water bypass * Forces
