I was wondering, did you have any problems with mold and rotting with your sponges and scour pads? This might be a stupid question but your filter inspired me to make one and I just wanted to make sure.
Not a stupid question at all. I've had the W/D a couple of months, and I've cleaned all the crates only once
(I clean the top crate maybe once a month or so)
I did not see any rotting or moldy matter in the scour pad or sponges because, if the bacteria in the nitrogen cycle are doing their stuff properly, there shouldn't be any molds or whole rotting matter. When I squeezed the filter media into the drums filled with water drained from the pond, there was just goo and dark dark stuff--very minimal if any solid matter.
