Hooked up a basic threaded "T" to my outlet line on my DIY co2. I just unscrew the platic screw in the "T" at night so no co2 enters the tank. In the morning,just screw back in and you back in buisness.

Just make sure it doesnt explode with all that built up pressure...

x2, I rather just run an air pump at night and don't have to worry about a huge mess. Plus it is much easy to get a timer and run the air pump.

Sounds like they're using a 2 way valve and taking the screw in valve stem out so their diy co2 vents to atmosphere at night, then replacing it in the am to seal the line.

This is correct.

The thing I'd be concerned about is your co2 mix getting accidentally knocked over and spraying out through the valve hole.

It's also a very manual solution to a problem I've never really had with diy co2, but by all means, if you can keep up with that schedule, more power to you.

Since it's venting to atmosphere there shouldn't be any pressure building. The only drawback I see is forgetting to put the valve stem back in. Am I missing something?

 

[MoeBetta]

If it's knocked over there would very likely be a rush of carbonated mix shooting up that line and venting itself all over the space.

It's still a carbonated solution.

either in the tank or on the floor... I would prolly rather it be on the floor.... I think its a pretty good idea, as long as the water doesnt back up into the bottle, make sure you have a check valve in place further up the line then the vent T.. other than that, good plan

I've had the unfortunate experience of my DIY CO2 mix actually making it to the tank. Nothing scares a planted tanker like turning the corner in your living room to see your previously crystal clear water now white and cloudy. lol I had to perform several water changes to get it to clear up. Needless to say I installed a check valve after that, but I would have definitely preferred it to spill in my stand or on the floor instead of in the tank. Not that the OP's mod will prevent that from happening...but I'm just saying.
