Unfortunately it is normal with manual regulator. Same problem has been reported so many time
Hi,
recently have started to use the pressurized CO2, using the Ocean Free Manual Reg. I have also installed a splitter onto the manual reg so that able to supply to both tanks.
Problem: Each time i set the bubble rate of both tanks, within 1 hr, it would stop flowing. I tried to increase the rate so that when it slows down, it would flow at the intended rate. But its the same outcome. the CO2 flow for both tanks stop. Have been trying to adjust the rate for quite awhile, but no use.
Please Help!!

So is there a solution to it?Originally Posted by Shadow

What is needed to be added?
or simply buy another unit?

I have 2 x 2L CO2 tanks using manual regulator. 1 of them is working fine. The other one, sometimes it works, sometimes don't. I even brought it back to NA and changed the manual regulator. But according to Mr Chan from NA, it is normal for manual regulator to have such problems. He mentioned that the problem may surface or disappear after you topup the CO2 tank. Solution? Get eletronic soleniod + regulatorI am also trying to find a manual regulator that don't have such issue. But to no avail.
I had also tried many times adjusting the bps. The CO2 flow also stopped after a while. But I do observed, if I manage to adjust the bps function normally - without CO2 flow stopping, it is when I complete the adjustment smoothly with CO2 bps increasing. If I complete the adjustment of the CO2 rate with CO2 bps decreasing, it will stopped after a while. You can give this a try.
I will recommend solenoid regulator. I don't see the point of buying another manual regulator which most likely have the same problem.
I do not know the real reason, my guess it is something to do with the pressure. Typically on solenoid regulator, it is automatically drop the pressure from 1000psi inside the tank to around 20-25 at the needle valve side. Maybe that is why it is call manual regulator, you need manually reduce the pressure to 20-25 psi before getting the right bps
Just a wild guess
I never have any problem with my manual regulator, but then again mine is a dennerle dual-gauge manual regulator ^_^
Does your dual gauge regulator reduce the pressure from 1000psi to around 20-25psi?
Yes it does. And its needle valve is super precise and reliable.
sorry off topic but...
By the way, I have seen on this forum people talking about a full CO2 tank is at 1000PSI, I believe that is inaccurate.
since the first day I have my regulator and my tank, no matter where I fill it up, it always read about 800psi when I get it back.
below is where I read from the internet from people who are in home brew hobby.
else you can search "co2 tank full 800psi" on the internet.
Co2 is a "self regulating gas", meaning the liquid in the tank adjusts to keep the pressure equalized to around 800psi, regardless of how much liquid is in the tank. So a full tank is 800psi, and a near empty tank is 800psi.
another one from an aquarium forum.

from what I read it ranging from 800-1100 psi depending on temperature. I have 3 tank all show 1000psi
Yeah probably dependable on ambient temperature.
My tank is showing 1000psi as well. JBJ solenoid. Been like this since i bought it in apr last year..
Hi all,
I finally managed to solve my co2 problem. In the end, went back to NA for a solution. Mr chan recommended me a 2nd hand reg without the solanoid for 3 red notes $30, but with a pressure reducer attached which reduced the pressure from 1000 psi to about 50 psi. so it is much easier to adjust the bps, and this time, the bubble count remains constant even after many days. The best thing is that since it does not have a electric solanoid, I do not have to plug it in to my already overloaded socket!
Maybe those facing this similar problem can try this method out. Works for me..

care to show a picture of this pressure reducer? fellow forumer may like to have an idea of how the device looks like.

The round part with the label "Golden Angel" is the pressure reducer according to Mr chan. Anyway, after switching to this reg, it became so easy to adjust the bubble count. For those who want to use something like this, but without using electricity, can try getting those electric solanoid, but manually removing the solanoid, so it will end up something like mine. However, by removing the solanoid, either you on it 24/7 or adjusting the bubble count daily, which isn't difficult to do so with the pressure reducer.
it is a proper regulator without the solenoid.
the regulator does not need electricity to operate.
however, a solenoid requires either ac or dc (less commonly used) power.

I bought my CO2 tank just about 1 month ago, without solenoid. Yesterday found out with a shock that CO2 tank all depleted leow!!! I bought from a LFS in central area. Not too happy about it, but will not go back there to refill anymore. I'm heading to NA later to get a solenoid and refill the tank!

I suspect when you bought the 2lt tank, the tank may not be full. cos even you on 24x7 with only 1 or 2 bubble count your tank cannot deplete so fast one.

OK. just got home from NA. one to one exchange with Chan, and got a JBJ solenoid.I'm a happy man! And my plants are happy again!
I got some duckweed to boot! Ha ha ha ha
