Coralife BioCube Filter Cartridge, 6ct (3 x 2ct)

Affordable and work great in my 29gallone biocube

Why do these filters come in diffrent sizes? They are for the same aquarium, I had bought these and they didn’t fit. Bought from a different seller with different measurements and they didn’t fit either. I decided to upgrade to the INTANK media holder , and although it’s expensive it’s worth the money. Take my advise. Get the intank media upgrade for the aquarium

Arrived as expected

WORK WELL, LAST

Too pricey in the long run

The filter is easy to use installing and replacing. It very good at trapping the dirt in the water causing it to clog fast (2 weeks). I rinse the filter with water weekly and change every two weeks. I think it could last longer but that routine works well for me in my Nano reef tank; it is a good filter.

Simplicity and the cost
