CO2

[Dave S]

How do I increase CO2, my current readings are:

PH 8.0, KH 9 and CO2 3

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

With a pressurized system if your having trouble getting the CO2 up. Maybe
you have too much surface agitation.

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

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..

Any ideas?

Hi Nikki

I'm using a CO2 Complet kit.(
http://www.aquatics-warehouse.co.uk/acatalog/aquarium_supplies_CO_2_KIT_132.html )
I've discarded the bubble counter and reactor and using another type or
reactor.

Thanks - Dave

[Dave S]

Thanks Craig - Yes, this week I did have a lot of surface agitation. I've
now adjusted the spray bar so that although there is surface movement it is
not heavy enough to encourage air.

The odour (I think) is the alcohol by-product of the fermenting yeast.

I too get a slight clouding when my mixtures are new and a thin white skin
thing on some of the rubber and suckers in the tank. I've read about this
white by-product on various how-to's and discussions about yeast generator
systems. According to all of these things I've read, there is no cause for
concern about the white stuff, it's apparently harmless and no-one seems to
know what it actually is. I have my own theories that it's a form of benign
bacteria from the carbonic acid, but apart from that I find the slight
milkiness in the water goes after about 4 or 5 days, when the mixture
settles down into it's middle period.

Sounds normal to me, to be honest. I house my bottles in a sealed bucket and
only ever smell the smell when I change or agitate the bottles (about every
two days).

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.

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..


Thanks,

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.

I also got a slight opacity of the mixture, I was new, fine white skin rubber and some things sucker tank. I already know this white by-product of various operations of the generators and discussion on the yeast system. According to all these things I've read, did not cause concerned about the white stuff, it was harmless, and no one seems to know what it actually is.
