I've never used the diy co2 method, so I can't comment on your problems.

I can say this though, diy co2 on a 125Gallon tank is pointless. It is
only
good up to about 20 gallons or so.

I works on my 50Gal/200L using two 2L bottles and the Tom Barr internal CO2
reactor.

I get ~15ppm, pearling and plant growth.

2 X 2L bottle systems (2 active reactors) would work in a larger than 100GAL
tank IMO.

either make yourself a diy co2 system using 2 litre soda bottles with

and suger or get a pressurized co2 tank. What size aquarium?


I have a pressurised CO2 system and have been using it for a week now.
Aquarium size: 400ltrs


How are you diffusing the CO2 into the tank water? You're using a
diffuser, not just bare tubing, right?

Hi Nikki

I'm using a CO2 Complet kit.(
http://www.aquatics-warehouse.co.uk/...2_KIT_132.html )
I've discarded the bubble counter and reactor and using another type or
reactor.

How many bubbles per minute do you have going? 40 bubbles per minute in
my 330l aquarium took the pH from 8.1 down 7.5.

Mine is running at 15 bubbles per min (this is as per the advice in the
handbook). I think I'll increase it by 5 (say) per day.

Oz, I'm running a pressurized system and I get the same film on the
suction cups, so it's not just related to the yeast system. I think
you're right about the link to carbonic acid.

It definitely brought my numbers up (there are only 3 small @2"
bullheads in there), and there is NO surface agitation...

I think I might try some of those CO2 kits, to see how they compare..

I recently experimented with DIY CO2 reactors.. although I was
pleased with the numbers, it seemed to cloud my water a bit, and I
noticed an
odour.

I am reasonable sure that no sugar/water/yeast solution made its way
into my tank directly, but, are there any side effects of the yeast
method? Were the clouding and odour just symptomatic of something
else?

I have since removed and discarded the contents of the reactors until
I can figure out what went wrong..

I have no problem getting 19ppm on a 55g using 2-2L bottles, swapping out
1 bottle every two weeks. I feed the CO2 directly into the venturi of a
powerhead and get a very fine bubble mist. A 125 is possible to do DIY.
4-2L bottles, rotating one bottle out a week, should provide plenty of
CO2.
