Messing around on sketchup the other day, and started designing a growout/fry rack. Not completely sure what size bins I'll use, so I just used the closest sterilite I had lying around for reference. The blue line is the "new"/filtered water, and the brown is the waste. The plan is to tap the PVC tubes above each bin and have the valves from jehmco with airline running to each bin. Each bin will be drilled with a uniseal in the back, and will have a 90° elbow act as an overflow, leading the "waste" water down to the sump. The plan is to mainly use this for growing out crayfish; though I'm sure I'll probably use it for fry at some point as well.
What do you guys think of this setup (sans container/tank size as that hasn't been decided yet)? Do you think it'd be a good idea to add drippers to each line in addition to the valves, or are they more than enough?
