MacFan will explain various types of CO2 reactors, the pros and cons of each, and lead a workshop to build a DIY reactor. DFWAPC will pay for all materials and then we will give away a few assembled reactors including powerheads as prizes. You have to be a paid-up member to be eligible for a prize, but as usual any plants that folks bring are free. If you really really want a reactor and don't want to chance being disappointed, you can buy your own powerhead (MacFan will supply brand and model number here), so you won't need to win one of the assembled ones.
I still have to upload a lot more pictures, especially how-to related ones, but you can find pictures of a lot of the tanks and the build out of some of them at our appropriately named blog site. (Look back through the history for all the photos).
They went to wigglers shortly after (unfortunately the pictures didn't turn out of those). There are at least three fry in the tank now. There could very well be more, the adult ones can disappear in that tank for months... and it's only a 12g tank! We need to put in some bigger PVC for a bigger "house" so the eggs can be inside next time. I didn't expect the eggs to be so big!
