Just been curious on this as i have other experience working with water.
What's the experience on growth in them, and how do you deal wiht it/try to prevent it?
I've got nothing going on of this nature in my formicarium (that i know of). But my experience is you can't keep a still/stagnate/closed loop of water that gets exposure to light(even the smallest amounts), and does not grow something eventually?
So just asking on this to see what the experiences are/what the things are we might do. As little of my xp applies here. Not options to cut off the light or add anti-fungal agents like copper sulfide to the water.
Thanks for any time and effort you have to give,
FFY
