Does this seem right, bubble counter video and questions. Leaking somewhere?!?

So I saw a video of some guys bubble counter and he had a big tank and very little bubble count compared to mine. I am wondering if I have a leak somewhere or if the video I saw was just really low amount of co2.

I run a cerges reactor with co2art dual stage reg and a SMC needle valve. PH is around 7.5-7.6 in the morning after a night of no co2 and 6.7-6.8 at night. I don't have any water leaking, that's for sure, but I don't know if the air is somewhere.

Here is the video of my bubble counter, the water is evaporating so its a bit low today. But you will get the idea.

How can I check for air leaks? Does this look like way too many bubbles? Its a 75g that's well planted with a few fast growing aponogeton plants.

That's really fast. Mine is about 3bps...maybe 4 on the 75g. Try checking for an air leak using a bubble solution (I just picked some bubble blowing stuff up from a dollar store) and drop some solution onto each possible area of air loss from co2 tank to fish tank. If you have a leak, you will see bubbles.

Do you have a lot of surface agitation in the tank that could cause co2 to escape faster?

Seems like a lot of bubbles, but hard to say watching on youtube. Could be because the water level is pretty low. Something I did with mine was to look at the properties of the video (your original) and figure out how many frames per second it is. Then find a program that will let you view the video 1 frame at a time. A little math and you should be able to figure out the bubbles per second.

For whatever reason, my bubble counter looses water also.

I think they all do through evaporation. But even with the level higher up it still is that fast.

I will try the bubble solution to check for leaks.

Surface agitation, is it too much?: https://youtu.be/7zP4WkPKOkM

Here is a quick video of my surface agitation, do you folks think its too much?


I also checked with soapy solution and couldn't find a leak.

The rate seems to fast in the video. Looks more like 6-8bps to me.. Try using mineral oil in your bubble counter. Its easier to measure a bubble count in my opinion and it wont evaporate.

Are you using co2 resistant tubing from the bubble counter to the reactor? Sure many people don't but it could be your issue. Why not try turning down the bubble count to 3-4bps and check your PH when the lights go out? If it's not dropping PH at 3-4bps you must have a leak somewhere.

Bump: Also your surface agitation is fine! Its all about creating a surface ripple without breaking the waters surface. You could lower your spray bar a bit lower if your worried about it. Looks fine to me though

Well I started slowly and the pH was lower at the time, as I increased the pH was dropping at what seemed to be a reasonable rate.

I am going to adjust my spray bar for tomorrow and see if that drops my more. Maybe I am losing too much at the surface, if that's the case its probably because of the agitation.
