In this video, I document the annual cleaning of the dirty sump, refreshing the Tunze 1073.050 return pump keeping the old one as a backup, and cleaning the Fuval eSeries 300 watt heaters.  I'll repurpose them for the RO/DI reservoir.  I also scraped a majority of the Coralline algae off in the refugium section.
