I am pleased to report that my mozzie/bug buckets are doing very well. 
One bucket I was trying to overfish the critters out so I could close it down but today I noticed thousands of what must be ostracods swarming.  These are the size of a pin prick, different to the few in there that are the size of a pinhead, maybe they are babies. 
The other bucket was very green, I put a new motherload of daphnia and ostracods in from the farm and over a week they cleaned up much of the greenery and there is just some floating stuff at the bottom.  Yesterday I was pleased to find about 6 live bloodworm in there.  3 of those went to the killies today and they just about went to nuclear war over them. 
I think I have Multi Bucket Syndrome, thinking of starting a bigger bucket.  My husband has even offered to build me a plastic lined trough for them  :lol:
