What CO2 tester are you using? The only one I can find in the store is a
little plastic deal that hangs inside the tank just under the surface and
has to be refilled with solution/water every so often. I'd rather have a
different kind.

thanks.

Well - in my opinion thats too much. I have about 1 bubble per sec on a 90
gallon tank being fed into the intake of a powerhead (802). The bubble
this
produces are REALLY fine, and at this rate don't cloud the tank up at
all -
infact a most of it is disolved in the first foot or so of the output
swash
of the powerhead. I had a reactor for awhile, but I found it just didn't
to
as well as the powerhead method. Without changing the bubble rate, I get
around 19 PPM of CO2 in my tank with the powerhead method and with on of
those spiral reactors (the one everyone has) I get around 8 PPM. Big
difference. I have to keep my KH at 80 to maintain the proper PH for my
tank
(6.8-7.0). I myself don't like putting it through a canister filter cause
of
air pocket buildup - I had that happen once, and when the filter finally
caught the airpocket (it had gotten rather large) it caused the pH in the
tank to fall by .8 (7.0 to 6.2) - I didn't think that was to good.

Aqua, is the amount of bubbles produced by the DJ50 overwhelming, as in
so
many they are floating all in your tank all the time, or are they
produced
every so often? What size tank do you have? I tried sticking my
airtube
into the intake of my Eheim 2028, but the amount of bubbles spit out the
outlet was so many, my entire tank (75) was almost filled with tiny
bubbles
rising to the top? So I now just have the airtube bubbling to the top
until
I find another way to diffuse the bubbles. I will give the DJ50 a try.
I'll also try adjusting the flow rate of the Eheim to see if that helps.
I
DIY jugs are producing at least 3 bubbles per second. Does that sound
like
too much or just right?

thanks.

However, How well does it disolve the co2 into the water? do you
ever
have
any wasted bubbles come out of the filter?

I have seen thousands of very tiny bubbles (much smaller than perling)
coming out of my DJ50. When they move towards the top surface, they
disolve
and disappear.

I am using Duetto Internal Filter (DJ50) as my CO2 diffuser. Have
a

Ok Ive started a new thread

Leigh Stated earlier
"I am considering switching to some kind of reactor, or
injecting
directly
into the filter intake, in hopes of lowering the maintenance
required.
You
do have to rinse the Eheim diffusor's ceramic disk every week or
two,
to
keep the CO2 bubble size small."

Is the eheim made for this, or are you just putting the air tube
into
the
intake line in the tank?

I have a Magnum 350, would the gas just create a large air
pocket
in
the
canister, or would it be disolved? Anyone tried this?

Thanks!
