I've been using the same filters for a couple of months now in some of my tanks.
These are the common carbon-sponge type that come with Regent HOBs.
About twice a month I swish them around in a bucket of water and try to rub any clingy stuff off of them.
Is this ok, or do I need to plan on changing them soon?
