Rinsing Tank Filter
I rinse my filter equipment media weekly. I have large, heavily planted tanks with a lot of fish in them and do weekly water changes of at least 50 percent, most times more. I find if I don't rinse them as often, the tank water gets a little cloudy.
I always squeeze the media in a bucket of the old tank water a couple of times to make sure the old plant and fish material is removed. I like to use media pads. They're very dense and do a good job of filtering out the little particles that float in the water and make it cloudy.
"Fear not my child, just change the tank water."
