I've decided to add a sump to my system. I'm planning on doing away with my HOB
fuge and Remora Pro for an in-sump fuge and better skimmer.
With that said, I am working on designing a plan to plumb my sump into my closet, which is 13" away from my tank, so it shouldn't be a problem.
I have a 20L tank that I plan to use, although I may go with a 29g. I have seen all the sites with design ideas and I'm comfortable with creating the sump itself, but the plumbing is the one thing I'm not confortable with.
I'll be running pipes about 3 1/2 feet down and about 6 feet across (behind the back of the tank, to the wall, through the wall, and into the closet). Is there a general rule about angles and length of pipes to minimize bubbles and noise? Should I make turns gradual or 90 degree? I know about the durso standpipe to quite gurggling, but I'm wondering what I should know about running the pipes. Or do I just basically have to get it to where I'm going?
Also, when calculating "pumping height" for the return pump, am I calculating total length of return pipe (horizontally and vertically) or just vertically? Also, with 5 MJ1200s overturning water in the tank already, would a 500/600GPH overflow be suficient for a 110gallon tank with 20gallon sump running an ASM G3 skimmer?
