Quads4-lif,
Regarding those pictures of the sump. Wow! That is a first class setup. I like the pvc design and the two overflows.
Mine is the bare bones cheap way out. I would've gone cheaper with a rubbermaid tub, but I wanted to see in the refugium.
Marineguys,
I'm no expert, in fact a novice, but I did get great advice from the folks on various boards on how to build one. Here is a great link somebody sent me to:
[Here's what I built with the hopes of getting an in sump skimmer someday:
sump
overflow box
Return from pvc
Mistakes I made were not making the return section larger so I'm always filling up with makeup water and not cutting fingers on the top of the baffles to keep the things in the ref. Not bad yet, but my macro algae isn't full yet. I have Kalkwasser dripping into the return section so I'm filling it up every two days.
Hope this helps,
Tom
