And just to add questions to a topic that has too many questions already...
I wasn't even planning on putting my samples under the scope until 2 or 3 days, but after less than 24 hours... I found this.
All my beakers looked like brown, stringy, bubbly happy dinos
...except one that looked like this
That's my What The Heck beaker. It's the only beaker with a treatment that no one would be willing to do in a tank.
Had extra dino and mix, put 1 drop of 4-12-4 miracle grow quick start in 50ml of dinos mix. My sketchy math says that's 94 ppm nitrate and 89 ppm phosphate!
So I figured I'd put it under the scope and see a complete dead wasteland. Nope.
Lots of micro life swimming. 1 species of dino totally wiped out, but the other (amphidinium) still moving but in very reduced numbers.
So weird.
