Einna, I'm syphon ing twice a day. It's SO ugly. I may be removing them. I'd rather scrape algae than syphon poo all day.
I hear ceriths/dwarf ceriths do the same job, but better.
The biggest help is small detritivores to futher break down the waste. Most of these are sand infauna...I think pods and bristleworms are two helpful ones that are fairly available. I'd be a little nervous of bworms in a nano, though
