While I was waiting for your reply, I stopped by the local Ace Hardware. I picked up a couple of ½“ bulkhead fittings that will work nicely.
I see a narrow-tubed re-circulating loop from the top of the reactor to one of the venturi fittings. I’m guessing this how you recycle excess CO2 from the top of the chamber, this is clever – I think I’ll do that as well. You also use a 2nd venturi to draw water in from the tank. Is this venturi suction alone strong enough or do you also use a Minijet or something to send water to the reactor?
One last question (maybe). Your design includes a lot of fittings and connectors. Is there any salt creep at these interfaces? Should I put a dab of silicone sealer into any of these threaded connections or is the Teflon tape adequate?
