They do the job
on 30 December 2012
They really filter, 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 two 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 two months if you thoroughly wash them like I do, making sure that all the debris has been removed.
Combined with the carbon foam and the zeolites, this plain 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.
