I put sand 1st then I put the rock and yes I rinse sand out. My tank is a yr old or more
When you put you tank together did you first place the sand down then the rock or put the sand after the rock?
It sounds to me like it is a detritus issue which is continually leaking into the aquarium. Could be built up under the rock work. Could be in the sand.
Did you rinse the sand when you set your tank up? How old is the tank?
