lewk Posted April 2 Share Posted April 2 Hello, I've been using a DIY Brine Shrimp hatcher that I've been pretty happy with. It's a hanging system that uses a CO2 cap to have separate airlines for aeration and for access, as shown below. Please ignore the mess - my setup is made for function, not for show. 😛 Anyway, I do have one issue with this setup - as you can see in the picture, sometimes when the air is disconnected brine will flow down the side with the check valve, which it shouldnt be doing. I'm guessing this is an issue primarily because of the check valves I've been using, as if the check valve was doing its job the brine shouldnt be able to displace the air in the valve, right? I was hoping someone has done something similar and can recommend specific valves. I know these clear ones are cheaper, but I do like the fact that they are clear - I know if BBS has gotten inside of them. I worry that wouldn't work with a metal check valve. Alternatively, if you can think of another way to avoid this issue I'm all ears. Thanks! 1 Link to comment Share on other sites More sharing options...
