I see, sorry I thought the DSB was in the display. stirring a SSB to clean it is cool.

It would be interesting to see the results from a biological Aiptasia filter. If you attempt it please track the results. I imagine after a year you would see a marked difference.

Perhaps an algae scrubber in tandem with and Aiptasia Nutrient Neutralizer would be a good combo. Throw in an area for cryptic sponges and your all set.
