I've upgraded the diagrams on my site, in hopes it better shows the "flow" of how the system seems to flow naturally.
After some research, I'm changing my thoughts about the skimmer. I think now it actually goes into chamber C instead of chamber D. (what do you all think?)
I'm still stumped. I suppose a downflow skimmer was the original design. Some sort of collection cup must have been at the top allowing an airstone and hose through. The original design doesn't seem very effecient, or wasn't for a reef tank.
Dunno, I think I might just get a BackPack skimmer.
Any thoughts about the backpack skimmer? I'm looking for a small efficient skimmer. It'd be great if it could fit in the Sump. (4"deep), or it'll have to hang over the back.
I'm still curious about whither or not I should keep the bio balls in the system or not. Does the bacteria that forms on them, compete in great part with the bacteria on the LR
? I don't figure they'd compete for O2
. Plus with the trickle down, I get great O2
saturation. Unless you think otherwise, or have advice, I'm going to attempt to keep them.
