My new 1/4 acre pond is about halfway full: ~6 deep in the deepest section. I added some FHM (maybe a few dozen) 3-4 months ago. I have not fed them. Seen none floating, so I assume they're fine (?) Regardless, it got me thinking that I'd like to test for zooplankton in general....how do I go about this? I googled it and got lots of highly involved scientific papers; I'd like to know if there's just a simple test I can do to see what's floating around in there....if anything...?
Thanks, and if this is a highly naive / newbie question, sorry....I'm learning!
