Sorry for the delay, between off hour calls from work and the GF driving me up a wall and around the state I've had little time to follow up on a lot of stuff.
I checked the troughs for daphnia, it looks like I have some. I caught some to move into one of my emersed setups so they could munch on the fallen flora and to get a population growing. Once they establish I'll more than happily throw some your way. The ones I had in the trough are slim, but will be hard to pick out from mosquito larvae. I've done my best, but worst case on the larvae that got through I hope my fly traps catch that live in the emersed setup.
As for the downoi, let me know when you're interested. I'll be free Wednesday night to package them up and meet, as well as Thursday night. PM me for details.
Another note, I'm thinking of a tear down of one of my cubes as I'm getting bored with Eco-Complete. If anyone wants a DHG mat that's around 4" x 5" let me know. I'll let go of it for $20 or let me know what you'd be willing to trade.
