Is this a good Idea to shut down CO2 at night?

yeast >===>bottle>===>valve>===>Tjunction*>==>regulator> ===>AQUA
+sugar



*
regulator
*
*
Balloon

(The * is also symbol for Tube ,just like the = )


.I was thinking that I could install a T plastic tube junction between check valve and aquarium ,and a regulator thingy ,like hospital IV ,for example, a bit further on the main tube..... run another tube from the T with a balloon at the end.On that tube ,another adjustable regulator thingy .So if I want more pressure in the tank ,I can shut off the balloon tube so everything goes into the tank.At night ,if I want to shut off CO2 in the tank ,I do it from the regulator on the main tube ,while opening the balloon tube clamp at max and let all CO2 go into the balloon.IN the morning ,squeeze the swollen balloon after having opened the main regulator.
I don t know if it would be a good idea ,I just put together some things I read about diy CO2. what do you guys think?

For DIY, it is the simplest to use a powerhead to spit the CO2 mist into the tank, turn the powerhead off at night, the gas bubbles out the top instead.

Wouldn't I have more control by adjusting the two regulators on the tubes,so I could easily balance the ph? I thought about a powerhead ,but it would only give me the ON\OFF option.

If you wanna take it that far just go pressurised as by the sounds of it your trying to re create a system like that is going to be a way bigger headache then you realise atm

And my diy is hammering along at 3 or 4 bps ATM and I have no intentions of reducing that either plants are loving it!

Is there such a thing as Too much CO2 then?I know it drops the Ph ,and suffocates fish ,of course.....but considering I will have a planted Betta tank ,what other things can go wrong? Also ,could I make it as simple as blowing a balloon and run a tube directly into the aquarium?

Don't even try it with DIY CO2. The plastic bottle would explode if you use a regulator or some sorts of valves to shut it off.... What you can do is to turn on airstone at night. This should gas of most of the CO2. In the morning, you shut off the airstone.

It might be more pragmatic to yank the co2 from the tank than tring to regulate a dyi co2 ssetup...

I won't be shutting off the bottle directly....the CO2 would either go into the tank ,or into the balloon ,which could explode ,i guess ,but they say yeast and sugar doesn t give you much pressure anyway.?

I have it run through a pump and turn the pump off at lights out and the bibles just float up and it doesn't saturate the water

But I run the pump into a upside down bottle with an elbow on the inside easily dissolves over 90% of the c02


Pressurised is a better way to go then diy yeast sugar mixes and is more stable as diy slows down as it cools off and sometimes can be really random in the bps count aswell

But running it how I do there's isn't a whole lot of pressure envolved and be sure to dril hole inside the pump were the filter media normally would go and run it so that the bibles float up to the impeller other wise you create a vacuum which you don't want

This is more likely for me.
