Spawning is sort of the equivalent of having fresh water plants flower in your tank. When it happens, you know things are going well!
Your idea sounds great, but I'm not sure you'll get a lot of export. Is this happening when you change out the culture water? You're definitely getting good nutrient recycling, with the food chain. I look forward to hearing how it goes!
I too plan to have a refugium with plankton-and ulva and chaeto-above the display tank. I'm going to take my time and establish a large plankto-population in the display as well, before any fish are added. I love that we're at the point in the hobby where we approach our aquariums as mini-ecosystems, not just a box of fish.
I've got to run, but I have more questions!
