All the outside Topias froze over solid. More than half of the big pond froze over. Little pond mostly froze over. I haven't seen that much ice since College.
The real question is what should we expect going forward this season? Should we expect a die-off? How about our vegetation, any issues to expect there?
Finally, what about the Biotics on the bottom and in the water column. Anything we should be looking for with them?
