My 30 gallon tank has been up and running for many years. I have a Eheim 2213 canister filter underneath, in the stand. The hoses that run to and from the filter to the tank have become quite filthy. I wouldn't call then clogged, but I have noticed that the flow has decreased. The idea of draining 90% of the water (and doing something with the fish) to clean the hoses doesn't seem very practical.
Does anyone know of a way to clean of safely flush these out? Is there some kind of plug that can be used in the aquarium side to stop the tank from draining if I disconnected the hoses?
