@ravenrae8 asked "How do you change the water with them being so small?"
So easy water changes are just taking water from the middle chamber or empty drum, so I don't catch any zoea. That works if I just need to reduce overall toxins in the water, like this morning. It's all connected through the mesh in the drums.
If I need to get waste out of the occupied drum, like sheds or food, I turn the filter off so the zoea sink, then shine a flashlight at the front so they move towards it. That helps get most of them out of the way of the suction.
Still likely to get a number in the waste water, so I settled on my system for that with my second change last night. Waste water gets siphoned into a bucket. I use a coral feeding suction pipe to get the bulk of the zoea out of the bucket, using flashlight to help gather them together. They go into a Tupperware I have. Then I do another round of follow the flashlight to gather them again, and use a pipette to transfer to a small jar. Then they go back in the kreisel!
Liking this system a lot so far. It's not really taking long, it's not a major strain, and I'm getting almost all of the zoea out of the waste water, without putting much waste water back in the tank.
Last time I just used the Tupperware to siphon into & spent entirely too long trying to find and transfer all the babies I could find. With 6 jars to do water changes on multiple times a day.... it was exhausting. This time is working much better so far!
