Eco-Aquarium Water Purifier Cube, Uscharm Carbon Water Filter Cube Easy Water Purification for Aquariums with Carbon Filter, Strong Absorption (Black, 10X10X10CM)

This product does not worked as advertised. Actually, it does not work at all. When I received it, it already was falling into pieces, and after putting in the water it gets worse. It’s really sensitive to touch and it gets destroyed as soon as you touch it.

This filter media is absolutely amazing! It works better because my fish tank looks great. before I add in the cube, the water was always a little cloudy, after I add those in, just laid them in the sump, the water cleared and my tank is crystal clear, Personally I think it well made, great for bacteria grow, it doesn’t restrict water flow and so far so good. highly recommend it. water changes(you still need to do water changes, at least once every two weeks)

Fell apart as soon as I tried to rinse it, took a month to get here!!

It is a 10X10X10CM activated carbon cube. It is very light weight and fragile.But Well made product. I was not sure about this purchase because I bought several kinds of purifier before and they all end up broken quickly. This one is different, very study and easy to operate. My fish babies are happy too.Absolutely cleared my tanks! Salt and fresh! Love them! I will be a permanent customer! Works great.... I'm ordering another one for my other tanks.

doesnt work like it said it would

I bought it for my horse water tank. I placed it in the filled tank. It immediately fell apart. I would never buy this again.

the product can be good but for the shipment they do not pack it well and I get everything

Works exactly like described, starts working immediately
