maybe long but probably less offort then baking / redoing the entire aquarium from scratch
you simply cap and wait ... even cockroach cant live with out air, even tho they can live an extreme amount of time with out it!
As it is the substrate is getting relocated, so I'm removing it anyway. Baking or boiling it off any having it dry should still take significantly less time/effort than waiting for all the snails to die, however long that may take, and still having to remove, clean, and replace the substrate from the large tank to the small one.
I am not ungrateful for the suggestion, as I'd employ it, to an extent, if necessary and in the future, but since the EC's getting moved anyway, I want the buggers to be dead in the event that I re-use it, sell it, or trash it. I'm not contaminating other people's tanks or public spaces with my negligence regarding this hardy species.
I can see why you would just want to start back from the ground up!
you would be left with a substrat of snail shells
And that's "early evening" for them after I killed off a while bunch with ammonia on Saturday. The problem's equally prolific in either tank and letting them gradually die off either from starvation or from CO2 poisoning will take a very long time.
omg that is ridiculous! what are they feeding on?
Can you imagine all the small ones that the camera didn't pick up or that won't show up in smaller images but that I can see? In any given 2"x2" area I see the gravel churning. They're living off of plant detritus, wood detritus, and the food they get to before my slow feeding animals have time to react to the presence of their 1-2x a week dinners.
