OK today's focus is on the sump. here is a picture then the explanation
the sump holds rougly 20 - 25 gallons of water, leaving ample room for tank drainage should the return pump fail.
notice the lack of baffles, there are none. the sump is long enough that any bubbles driven into the water column have more than enough time to rise to the surface before getting to the return pump of the furthest left. both the tank drain and the skimmer outlet are on the far right.
to the far left is also an algae screen, hard to see but there is a power head under it that pumps water up into the pvc frame which is squirted through an outlet on top of the screen.
the stack of egg crate and pvc pipe, in the center, will eventually be totally covered by rubble on all sides and the top, I just dont have enough rubble yet, this is done to create my benthic zone, with lots of surface area for such lovely natural filters such as sponges, tunicates, spirorbid worms micro dusters etc to grow and attach as well as to begin to accumulate sludge.
the skimmer is the only one of the old skimmers I have that still functions. its a coralife SS125, not my first choice but it runs and skims and has lasted me for years so it shall run untill it buys the farm.
and that my friends is an overview of my sump. exciting isn't it. well maybe not, but I realized I kind of glossed over the sump in the build and never really explained my plans well.
