Co2 bubble counter and less bubbles

[Wrona0306]

Hi everyone
I thing i have small problem with my pressure co2. I set up bubbles counter for 2.5 bubble per secound , selenoid velve shut down co2 in evening and next morning when selenoid velve turn on i had only 1.5 bubble per sec. Anyone know why this is happend?

Well, it sounds like you may have a particle stuck in the body of the needle valve. You could try opening up the needle valve for a moment to see if the particle dislodges itself.

1. Is your bubble counter integrated with the needle valve or is it separate?
2. Do you use a check valve? If so, where is it located?
3. How much pressure is on the line going to your diffuser or reactor?

There are a lot of members on this forum that use CO2 injection, so a little more information can help us determine what is going on.

I send some pictures becouse this is my 1st co2 system. Bdw yesterday xo2 shut at 25 bubbles per second and this morning when co2 was turn on was 22

OK well 2.5 BPS to 2.2 BPS is not bad: the rate may fluctuate some and your plants will not know the difference. If you want more accuracy you can purchase a pH controller like this https://www.amazon.com/gp/product/B01NCQUSSJ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1. The question that I have is why do you have to run 57-58 PSI for the diffuser line? 40-50 PSI should be good, but some diffusers require only 30-40 PSI. You should probably lower the diffuser line pressure and open the needle valve more.

Hi
My co2 regulator dont have this option. When i open buttle this pressure i have and i cant change it. Mayby is different option how change it this pressure or buy better regulator, for example co2 art with that option.

Ok. I researched your regulator and you are correct: your MuFan regulator does not have an adjustment knob for line pressure. Unless you are rich and have deep pockets I would try to live with it. You could still attach your regulator to a pH controller to ensure that your aquarium stays at the proper pH level (optimal window).

if you ever do consider to get another regulator in the future,
I would look into a Green Leaf Aquariums or CO2 Art product. These are mid-grade regulators and work well for aquarium use.

Thank you
Probobly in near future will buy regulator from co2 art but no spare money at this time so will use what i have.

OK. CO2 Art regulators have good reviews and I think you will be pleased.
