So after playing with this a little bit and googling images of other brine shrimp hatcheries, I think I figured out how this should be set up. Would have been nice if the listing had at least one picture of it put together. I put together a mock setup in one of the photos. If you follow that, the silver air control valve and the clear and black check valve should be in the airline and not just next to it. I just didn't put them in yet since I wasn't sure what lengths of tubing I would want. My guess is I will want everything short except the check valve to the air pump.The way this is designed, I can see good aeration getting to the shrimp, but the moment you turn off the air pump to get ready to harvest, you are going to have baby brine shrimp trying to get down both tubes at the bottom and not just your collection one. One thing I would recommend is to turn off your air at the silver control valve FIRST and then turn off your air pump. Hopefully, that will keep them from getting past that checkpoint. I would also make that checkpoint as close to the tubing split as possible to shorten that distance. I would also shorten the collection tube so you don't have to figure out how to get little shrimp out of a longer length.A bit of extra information for anyone who is looking at this and has never done brine shrimp before. Brine shrimp need lots of oxygen, hence the airline to your air pump (not included). The shrimp are phototaxic which means they try to go towards light. The reason for the black wrapping around the body of the incubator is to encourage them to head towards the bottom when they aren't being shoved around by air bubbles. You can aid your harvest by shutting the control valve, turning the air pump off, shining a flashlight as close to the bottom as you can (or ideally on the collection tube above the white tube pincher), and then waiting 10 minutes to let things settle and your shrimp to move down. When you come back, you should see a lot of orange color in your light. That is the baby brine you want to harvest. Do not move the incubator or you will have to wait some more for things to resettle. Get your collection container ready (they provide the medicine cup but you can use anything), put the end of the collection hose into your container, and then open the tube pincher. Try to only dump out the orange section of the incubator since that is where your brine shrimp are - anything else is mostly just salt water.There is more to brine shrimp than that, so I recommend you look up how to grow them online. The information I gave above doesn't include things like getting the salinity of the water correct. They aren't that difficult, but there is some complexity to them too. Doing your research will help you be more successful in the long run and not get as frustrated.Overall, this kit should work, but there are better ones out there too if you really get into it.NOTE: I have no idea about the double-sided suction cup as I have never seen anything like that before. Also, quality control was slightly lacking and I am missing a pipette out of one of the kits. Finally, note that this kit does NOT include any brine shrimp cysts so You'll need to get those separately.

Works ok for small batches of baby brine.

It’s literally the size of my hand. It also has 2-3 pieces missing. Mainly to even attach the tubing to the canister itself. Will be returning and getting a refund. For as much as you pay for it, you might as well just buy the parts to covert a 2L soda bottle into one…

This this does not work and doesn't come with instructions, it's confusing to set up.
