Pond water slides and water deoxygenation
Posted: Mon Apr 19, 2021 3:41 pm
Hi all,
I'm thinking of making some of those slides that use petroleum jelly to seal the edge so they don't dry out so fast.
Thing is, I've also noticed that I need to leave the lid off the pond water sample if I don't want it to go anaerobic. Currently there's quite a nice little ecosystem pottering along there.
So putting those two facts together, I'm wondering if, over time, the thin film of water under the coverslip will suffer from deoxygenation, thus killing the very life I'm trying to observe. I have an LED illuminator, so there's no heat to speak of.
Best,
Markus
