Flow in my nano

[karazy]

haha, its just the return from the sump, but i don't really want any powerheads in the tank or anything.
also a closed loop would probably add too much flow for the corals i want to keep.
Oh, and its a glass tank

Duh...its an already assembled tank
I think you'll want a powerhead or two, for the flow you need going through the sump, you'd have to get a big sump to be able to utilize flow like that. I had a dart for a return on my big tank...full bore...but my sump is 8 feet long and it was no problem.

hmm.. well i think i'll get an about 700-1000GPH pump and then put a gate valve on the outlet so i can tone it down , and then add a powerhead if needed

Hi karazy,

Why not have your main drain, backup drain, and return all inside your overflow box? I am building a similar setup next week (stand is built, tank is drilled), just need to finish the acrylic work. Going to have the return come through the side of the overflow, and into a loc-line Y with two duckbills. 3/4" pipe. I'll post pictures once its done

Actually, I'll +1 that... I thought of that but it wasn't one of the offered options

that actually sounds like a good idea.
i'll have to think about it because i kinda like option #2 maybe a bit more than the return going through the overflow box,
just cuz it makes the flow more spread out IMO
