So my shrimp keep swimming over the weir, there is a durso stand pipe in and they seem content to swim/hang out on the pipes, and im having heck of a time trying to catch them. The flow is 600gph in a 24" tall 15x15" triangular space. I was thinking I could throw some miracle mud, live rock gravel and chaeto in the overflow and put it on a reverse photosynthesis. Please let me know what you think.
