Review on Gallon Aquarium Divider Suction Cups by Ashley Cook

Let me start by thanking the company that made this who chose to install extra pins for each divider. I broke 3 pins trying to install the spacers and luckily they gave enough to allow me to reassemble them. Haven't tried these dividers with my fish as they haven't arrived yet but they look like they have good flow and although awkward to assemble they seem very strong and are perfect for my 20 gallon long tank.
