How clean do you keep your sump?

[eli@fijireefrock.com]

I have never cleaned my sump until the move and don't intend to as my sump is always filled to the top with rubles and live rock that doesn't fit proper in my display.
Next build I will have 2 sumps for the same reason filled with rubble rock as a sess pool for pods feeding my main display.although my fragmentation tanks act as sumps to and keep those as clean as possible.
