Green disc with CO2 bottle

thats exactly what its for. between regulator and the bottle. they are 1 and done, it needs to be replaced every time you get the bottle filled.

Thanks, didn't know if it should be used in this situation or not.

there are re-useable seals that can be purchased. they are called perma-seal. green leaf aquariums sells them for i think $6 but i honestly dont like them because they are leaky and i broke my last 1. just remember your going to need a new seal next time you get a refill

I use perma seals on 2 co2 tanks and works fine for me. I use the ones from aquariumplants. Bought them last year and still using them. Either of them is fine but you need one.

Appears that a new one comes with each bottle I exchange where I get my CO2 so don't think this will be an issue.

Thanks
