They work well to keep the water clear
on 30 December 2012
They really filter and clean the water, so I can't complain about them. I find that I can reuse them a couple of times provided that I wash them in tank water when I do my water changes, they will last about three months before they look like they need to be changed. If you can afford changing them every month, it probably is best but if you can't, each foam will probably last you three months if you thoroughly wash them like I do, making sure that all the debris has been removed. I do not squeeze the carbon foam while I am washing because you will see that carbon will come off the foam, meaning that there is less filtering agent to perform the function, so if you vigorously shake it side by side in the waste water inside a bucket, it will most likely remove most of the stuff that gets stuck on the holes.
Combined with the plain foam and the zeolites, this carbon foam makes sure that your aquarium's water is always clear and clean for your little buddies :) I think that they are priced fairly as they last a substantial amount of time when you consider what their function is, so I would stock up to make sure that the water is always clean, after all you need to consider that fish live in their own waste.
