Construction

This evening, I pulled out the sump/refugium under the 29g reef to make a couple of alterations. I needed to trim the baffle before the return section about half an inch, to create a slight downhill momentum so the water in the refugium would not tend to stagnate. Microbubbles have been collecting there on a daily basis, and I've been swishing around a piece of plastic to stir up the surface daily. Once the sump was drained of most of the water, I took it into the garage and masked off as much as possible to avoid dropping any acrylic shavings into the refugium.
