Diy co2 questions

Sorry guys I know this topic comes up a lot and I've tried researching but haven't found any answers for my first question. The second question I've seen answers like "possibly a leak somewhere" but I'm not sure if that's right or if maybe it's just the container I'm using for the bubble counter.

I just setup my diy co2 last night (yeast sugar and baking soda mix) the mix is in an ocean spray juice bottle but my bubble counter is a glass dip jar.

So my first question is. ... is it ok to use the glass dip jar for the bubble counter? Or will the pressure become too much for the glass to handle and explode?

I'm not getting any co2 in my tank. I'm using an air stone and check valve and it's all been tested for leaks (by blowing in it) I am getting about 1 bubble every 3 seconds in the glass jar but nothing in the tank.

Is there not enough pressure to push co2 through the air stone?

I'm so lost please help!!!

You probably still have a leak somewhere after the glass jar

Test for leaks by spraying soapy water on the connections.

Does anyone know if the glass jar is ok to use or will it explode? Right now that's my main concern! I will check for leaks again but first want to make sure the jar won't explode lol

There's really no reason for a bubble counter on a diy co2 system it's not like u can adjust it anyway I run diy out of my bottle I run a short airline to a check valve then airline into tank I've never had an issue I use regular yeast at 1/4 teaspoon to 2 cups sugar and 2 table spoons of molasses my 2L bottle runs around 9-10 days before needed to be switched out

My mix is a little different though. I used 1/4 teaspoon of yeast 2 cups sugar and 1/4 teaspoon baking soda. This is my first ever diy co2 setup so the bubble counter was for me to see how soon my mixture needed to be replaced and also to make sure I was getting any co2 at all. Is there any other way of telling when the mixture needs to be replaced? If so I may just skip the bubble counter all together!!

May not be enough pressure for the airstone. Glass jar should be fine , very little pressure there.

Just watch your defuzzer when bubbles slow down it's time to change bottle don't wait till they stop you will see the difference also as the day warms up more co2 seems to be produced so just pic a time to look at bubbles around same time each day it's worked for me for a long time now with no real issues at all adding baking soda is fine they say it keeps ph more stable I personally don't use it but there's nothing wrong with using it , I am also using a modified elite mini filter as my difuzzer but airstone will work too

I took the glass jar out of the equation and it's working fine now so there must not have been enough pressure.

Thank you everyone!!

I'm not seeing much direction (besides up to the surface) of the bubbles though. I've tried moving my spraybar but it doesn't seem to be pushing the bubbles much :/ I'm hoping enough bubbles disolve before reaching the surface so this entire thing wasn't pointless lol

I had the air stone already which is why I am using it but I may need to switch to something else just don't want to spend a lot of money.
