I usually run between 10-30 psi on the regulator output --
each system have somewhat diff demands due to diff
conditions or equipment.
I can't imagine a stable system at 3 psi, although I'ms
sure someone has done it. But at that pressure, it would be
difficult to have a needlevalve offer much control over the
flow, every slight change in pressure will change the flow.
Scott H., who realizes that for everything that almost no
one does, there is at least one person that pulls it off.

Yeah, this is good stuff. I've noticed the same problem
recently, and I
was told to run my CO2 at 3 PSI! When I get home I'm
kicking it up to
10. Thanks

I have read of other users reporting or eratic
performance due to A) the
low pressure side too low (some need to run ~30PSI, I run
~10) and B)
metal shavings in the needle valve to other problems like
reported below
that were solved by a cleaning/service.

Hey Matt,
I had a similar problem with a JBJ regulator. There
was a gasket that
went
between the bubble counter and needle valve. While
filling the bubble
counter,
this gasket fell off. My bubble count was eratic just
like yours and
required
me to turn it up every day for about a week. Once I
figured out the
gasket had
fallen off and I put it back where it should be, things
were fine. I
recently
set up a three way splitter on one of my regulators.
Three bubble
counters (JBJ
brand) were included with the splitter. Not a single
bubble counter
had a
gasket included with it. I mamaged to get some gaskets
that fit
between the
bubble counter and needle valve and they all work fine
now. I'd check
to see
if your gasket is missing. The CO2 will choose the
path of least
resistance
and come our of the bubble counter versus pushing
through the tubing
and into a
reactor or diffusor.

Subject: [AGA-Member] Co2 problems!
Hello all, My name is Matt and Im fairly new to this
orginazation but
it is
a pleasure to find and be a part of it. I'm having a
problem with my
newly
set up pressurized co2 system. A few weeks ago I
ordered a AZOO
pressure
regulator with magnetic valve, and needle valve. After
it arrived I
went to
a local welding supply house and picked up a 5 lb. co2
tank went home
and
set it all up. I adjusted the co2 flow to the desired
amount and all
seemed
to be working great and continued to work so for about
a week or so.
Any way about a week later i was observing things
and noticed
that the
amount of pearling in the aquarium had decreased so i
checked over
some
things to find out that the problem appeared to be
that less co2 was
being
released from the regulator. So i checked things out
there were no
leaks, my
check valve on the air line tubing is working fine but
still for some
reason
a lesser amount of gas being released.
Not knowing what the problem could be i adjusted
the needle valve
opening it a bit more to get the desired bubble flow
(around 3
bubbles a
second or so) and it continued to work fine for the
rest of the day.
At
night the lights shut off and so does the timer for
the co2 valve,
and in
the morning it comes back on with the lights. So i
figured I better
check
things out to make sure it was still working properly
only to find
that the
flow rate had slowed down again to almost nothing....
maybe about 1
bubble
about ever 5 to 10 seconds. Not my desired level.
Baffled by what
appeared
to be happening over night I checked ever thing over
again looking
for leaks
making sure all was hook up tightly with still the
slow flow I went
ahead
and opened the needle valve further back to the
desired flow rate and
once
again things worked fine for the rest of the day. at
night everything
shut
off, and in the morning when it all came back on I
checked things out
to see
what was going on.... with the same result as the day
before.... for
some
unknown reason the flow rate has slowed to almost
nothing at all. I
cant
figure out what would be causing this? has anyone else
ever had any
problems
similar to this? or have any idea at all what could be
causing this
strang
decrease in my flow rate after the magnetic valve
shuts off and then
comes
back on in the morning?
From what I under stand I should be able to set
the needle valve
to a
desired rate of flow, and every time that the magnetic
valve opens
again it
should resum at that flow rate making it all fine to
be left alone
every day
until the tank needs refilled..... and I cant figure
out why things
would be
acting in the way that they are..... Any help at all
that could be
offered
would be GREATLY appriciated..... I am fianally
getting things with
this
aquarium to a point that I am really pleased with it
all.... but this
has
been testing and rather frustrating to say the
least.... espically
after
spending a very nice sized piece of change on this
equipment to get
the
desired co2 levels i wanted in my tank with out having
to do daily
maintance
to achive it..... thanks a lot for any help you can
all give me!
Sincerely,
Matt Scarnecchia
Youngstown, Ohio
