Yep, 40x objective seems about as high as you would want to go. At 100x I squashed cells lol before I got in focus. 10x or 20x 25x all should be fine to the view the 40x.

Without reading the whole thread, anyone try running low micron filter sock for a while to see if that does anything?

I ordered some 1 micron socks (not sure how long they will last before clogging). Will try to blow stuff off the rocks and run water through the sock. For now I installed whatever brs sells, think those are 200. Usually I do not run any, but I guess it won't hurt to catch some of these guys and swap socks once a day.
