Coralife 6-Pack of 2 BioCube 🐠 Filter Cartridge for Aquarium: Ensuring Optimal Water Filtration Review

These filters work incredibly well. I have a 30 gallon bio cube that is heavily stocked with a variety of fish/shrimp and I rarely have to worry about the water quality. Between filtering, planting and changing the water (e.g. monthly), my tank is doing great.

These filters work well and as expected. They keep my aquarium clean and fit snugly into the Biocube's filter slot. They do clog up with dirt very quickly though, so make sure you have a few on hand. I change every few weeks.

ok filters or what i need and works fine for a 32 gallon bio cube, i was very disappointed that a pack of 2 filters was 7.99 / two months ago / and then someone decided to change the price for a pack increase to $20. Do you think Amazon will investigate these dishonest practices?

These filters usually work very well with the Biocube. However, after not being able to find them at my local store, I ordered them here. It turns out those filters have been recalled since February because of some type of chemical contamination. At first I didn't smell it, but when I got home from work and found lots of dead pom pom crabs and snails falling off the jar, I smelled a strong odor of gasoline. The whole box smelled of gasoline. Until you fix this problem, don't buy!

Great deal... And cool filters!. I'm pretty sure you'll need it if you buy because you don't have a choice... But at least it's a pretty good option if you're out of options lol. I can use these filters multiple times. This dirty filter can be easily washed in the sink and used again and again. I usually only need to buy one of these packs every now and then. Amazing that it lasts so long and I don't have to think about buying new filters for my saltwater aquarium. My happy fish stay happy.
