🐙 Reef Octopus Media Filter Kit 4 Inch Chamber with Pump - Perfect for Beginners Review

There are two of them. The work is excellent. I use one for bio pellets and the other for charcoal. Great flow through both and the biopellets tumble well.

Very large I underestimated the space required and placed it under the tank. Worked fine until the water level dropped and the pump ran dry. But it is a very well made product.

Large capacity. The only thing I don't need is a pump without a foam filter. The media gets dirty very quickly at 180 gallons. I bought a nozzle with a large sponge and use that instead.
