and get some credit for it. When you do your water changes you can pull the entire clump out and rinse it in a bucket of old salt water to clean the detritus out of it. Is there sand in that section of your sump or is that accumulated gunk? If it is not sand then when you do a water change I would remove all of that stuff and rinse the cheato out as I mentioned.
