DIY Overflow concept for Saltwater tanks, with diagrams, pictures and instructions.
This little tool is incredibly handy. The first advantage is clearly the ability to direct the siphon exactly where you need it. I use this for a variety of other purposes: from gently scraping algae out of hard to reach areas, having it in position while I trim off hair algae/caulerpa to suck up the clippings, getting at cyano growing underneath the substrate up against the glass. It's for targeted, non-destructive cleaning of your nano/pico tanks.
