Plumbing Part Deux: How long has it been since sumps have been discussed in detail. I remember someone bringing a sump to the meeting at Cass's place, but there wasn't that much discussion. We touched very briefly on the subject of sumps at the March meeting as we discussed plumbing the return line, but a more thorough discussion of sumps would include:
design - refugium or not, two inputs or one, filter sock or some other method of coarse filtration, air bubble baffles, placement of bulkheads, volume reserved for tank overflow
pros/cons of internal vs. external pump
sources of acrylic/ how to drill, cut and glue
If I had known then (8 years ago) what I know now... I wouldn't be on my third DIY sump!
