MarineLandBio-Filter Balls, 90 Count, Support Biological Aquarium Filtration, Rite-Size S, T and X, Fit All C-Series and Magniflow Canister Filters

Great value. Works well. Easy to use. Helps with algae.

Worked as they should, good price.

These work well to promote a healthy environment for fish, would recommend buying these.

I have a multi stage canister filter for my 125 gallon tank. These things work wonders in keeping my tank clean. A quick rinse every so often when I pull the filter off and they are good to go. They work so well, I started using them in my small outdoor pond (40 Gallon or so) and they helped keep my pond clear all summer in a homemade bucket filter.

Bueno

I received these bio balls in the mail yesterday,and they are small but perfect for bio filtration. I purchased these for a large hob filter to have extra space for useful bacteria to have more area. They are good quality for the price . Easy to use. I rinsed with hot water and put them in. I will update at the performance asap. Time will tell as to how long they last.

I’m no expert at this and it’s always a learning process but these balls have changed the game for me. The water stays clearer and the smell is like pretty much gone. It’s been a struggle trying to find the right equipment to tend to these messy turtles but I can say these balls help a lot right now and until I can afford a canister water filter this is a great purchase.

I’m going to be honest and admit I have no idea how these get used. But I dumped them In a basket in my penn-plex cascade 1000 canister filter on my 55 gallon tank stocked with 11 gold fish, and a turtle. Ive had absolutely no issues with the water, my water has stayed clear, they all fit in 1 basket in the filter.
