With tank water yea

 

The filter is only going to "clean" to a certain extent. Its really there for your beneficial bacteria to colonize and eat up the junk in the water. If you change the filter cartridge, you're going to reset your cycle. Best thing to do is a water change, and when you remove the water from the tank, pull the cartridge and rinse it around in the old tank water and throw it back in.

I had no idea.so I throw it out yesterday but the foam that's there has been in since I first set the tank up is that ok since I threw it out already

 

Anything out of water will die pretty quicker. Your bio rings and foam should have a bunch of bacteria. Just watch water parameters for the next 3-4 days.
