I have a wet dry filter with the blue Bio balls, and a RIO 2500 pump. I have a lot of dirt or sand in the bottom of the filter, in the section where the pump is. When I take a flash light and look, I can tell that there is a collection of stuff that is in the clear tube that goes from the pump to the tank. What can I do about this? Should I be alarmed? How do I clean it?
The biggest problem will be Nitrates! You should slowly and only a few at a time remove the Bio Balls and replace them with Live Rock Rubble.
You can siphon out what is laying on the bottom. As for the hose, If it has alot of build up of algea and crud it would be easiest to just a new peice at your LFS or hardware store and replace it.
