How to get CO2 for 55 gallon

Perhaps it's because I don't have any background that it might seem to me
like you are rushing into CO2. Have you had planted tanks before such
that you know you need/want CO2? Most of my planted tanks do not have
CO2 and it means that I don't have to prune quite as often ;~). My CO2
tanks keep my pH low which is fine for the fish I have in there. I don't
have any plants which require CO2 to do well, and having over 100
aquariums, mostly planted, I'd be willing to wager that there isn't
anyone here with a bigger selection (I manage a fish store). Light still
seems to be the first constraint. CO2 injection with poor light doesn't
get you much further than if you didn't have CO2.

Have you measured your kH yet? The value of an automated injector
monitoring your pH would depend on whether your pH was likely to change
much, which would depend on your kH.

Having used flourite and gravel, I don't think I'd spend the extra for
flourite again. There are too many more important growth factors ahead
of whether your gravel is stone or fractured clay. jmo

I guess it depends on your level of expertise, your objective and how
quickly you want to get there.

I'm trying to follow your advice! Actually, I'm looking into as many
possiblities as possible. Right now my tank is sitting empty in my
room. I've rushed into tanks before but I want to research this one
and start out right. (Plus I'm still looking for a place to find
flourite at a decent price).

I will probably go with one or two of the DIY CO2 injectors for now
but I figured I'd look at what my options are as far as the more
elaborate CO2 injectors on the market. In the long run, isn't it
better to have an automated pressurized system that will keep track of
pH?

LOL, you don't sound like you are following any advice in this
thread,
but as long as you are still learning and we are giving you ideas,
then
it's all good ;~) Your phone book should have listings. Many
industries
use CO2 so it's readily available, but prices will vary.

Before installing the CO2, it would be instructive to know what your
gH
and kH levels are. I don't think CO2 injection would do much to my
tap
water when it's at 35dgH 16dkH, and if you are at 3dgH 2dkH then you
might be pearling your plants and looking for a way to periodically
turn
off the CO2, so like so many aquaria questions, the answer is 'it
depends'.

I've found several vendors on Ebay that will sell me a CO2
regulator,
a pH meter, some funky black thing whose name I forget to regulate
bubbles. The bundle comes out to about $250. I'll willing to
spend
that money. My question is - where do I get CO2 tanks. I'm an
EMT, I
know where to get O2. But where does an aquarist get CO2?

Also, my water has a high pH (about 7.6-7.8). I know adding CO2
lowers pH which would be good for the tank. I'm now sure what my
gH
and Kh are. Would using a peat layer underneath my gravel be
beneficial?

Sounds like you actually have a 75 gallon rather than a 55. Four
55w
CFs would give you a nice amount of light, but very close to too
much
for a non-pressurized CO2 setup. I would aim slightly lower if
you
plan to use DIY CO2. But still, if you have the patience to keep
up
with them, a couple DIY CO2 bottles will work for you. I wouldn't
waste any money on off-the-shelf DIY CO2, they are no better than
regular DIY yeast/sugar mixes, save the money for a pressurized
setup.
As for the lighting, again probably a little too long, I'd start
with
10-12 hours and see how things go, you may find yourself reducing
it
if you run into any problems. Filter wise, the 2217 is what I use
on
both 55 and 90 gallon tanks so I know that will work very well
for
you. The 2028 is just as good, pretty much the same size, a
little
bigger media storage I believe but very much the same. The HOB
you
can
throw out the window, it's only going to reduce your CO2 levels
and
it's not needed as any one of the other filters you have is more
than
sufficient. A good size fish load may also help maintain higher
CO2
levels, but obviously don't go overboard. As for the substrate,
flourite/gravel mix works well, I'd add a handfull of peat moss
to
the
lowest layer along with 5-6 crushed Flourish Tabs. Then cap it
all
with 3-4 inches of flourite/gravel mix. I don't think you'll be
able
to maintain such a steep slope for too long (4" in back, 1/2-3/4"
in
front) plus that could cause nutrients to come out of the lower
layers
of the substrate. I'd go with 4" in the back and 3" in front, all
the
same gravel/flourite mix in case you decide you want some
foreground
plants in the future.

I did check my parameters tonight. kH 8 and gH 13. Those are the
parameters in my existing 25 gallon. It does have one large piece of
bog wood and a couple of fist sized stones all from the lfs. Right
now these numbers don't mean much to me since I've never paid
attention to them before.

I'm so confused. There are so many variables: CO2, substrate,
lighting - and I'm getting so much advice. Maybe I should just fill
the tank, try it out and fix things that don't work as I go along?
I'm trying to set this tank up right but the "right" way to do it is
getting very murky.

The amount of data available can be mind boggling. It's better to start
at the beginning. If you want a planted tank, you need light, water,
plants and nutrients (which you get from the back end of a fish after it
is fed ;~). Assuming your typical lighted tank (ie: 0.8 watts per
gallon), this arrangement will grow a variety of plants, slowly at first
and then they will pick up speed a bit. Some will not grow well, so you
will not be 100% successful (50% is pretty typical). You take your
victories and work with them, typically keeping about 6 to 8 types of
plants. You can stop here, #1.

Your next plateau is a lighting upgrade to around 2 wpg. This is enough
to see a noticeable difference in plant growth but not have the algae go
crazy. Your victories will grow faster, and some plants which had been
labouring will start showing more promise. With the investment in
lighting, a substrate change is usually attempted at this point, to a
finer gravel. You can stop here, #2.

Next plateau is either upgrading to around 3 wpg and/or adding CO2 (they
tend to go hand in hand at this level, as well as another substrate
change). With CO2, your victories might become a nuisance, but pruning
keeps them under control. Plants which were labouring will show new
growth. Some plants will die and there are still always plants which you
cannot grow, but the list of failures get shorter. Some of the plants
which seemed to be doing badly under the new higher light may return from
the dead with new leaves which don't burn so easily. Plants are
extremely adaptable, and with high light and CO2, they have a source of
energy to make their corrections. You can stop here, #3.

With CO2 and high light, it is like your aquarium is a time machine,
where time moves very quickly. Not only do plants grow quickly, but they
quickly strip the nutrients out of the water. At this compressed time
scale, when plants hit a constraint (ie: some mineral), they either hit a
wall (stop growing), or their rate of growth quickly diminishes as their
momentum is carried by stored energy, instead of water column nutrients.
Various symptoms appear (leaf coloration, growth rate etc). Enter the
world of adding fertilizers. There are automatic dosers, or you can do
it manually, weekly to daily, adjusting what trace minerals you add by
the visible symptoms. As long as things are becoming more automated, a
pressurized CO2 system starts making more sense. You can stop here, #4.

Ironically, aquatic plants (which suggests a very natural biotope) can go
from one extreme (no filters, no artificial lights) to another extreme
(very scientific and technical). There is no right or wrong, you decide
where on this scale you feel most comfortable, and the scale above was
quite arbitrary. You can mix & match and I'm sure everyone advances
through differently. I'm responsible for over a hundred tanks and while
they range through the first 3 categories, most are between #2 and #3
(non-CO2, fine gravel, under 1.2 wpg with a heavy fish-load (natural
fertilizer)), and the plants are gorgeous. My pruning load is acceptable
and I've found 3 plants which I cannot grow very well (out of hundreds).

If you are not sure where you will position yourself, then try not to
make any purchases which will restrict you later. Canister filters are
plant-tank friendly. A lighting upgrade is always a good investment.
Fine gravel is plant friendly. CO2 can always be added later. I
personally wouldn't waste much time and effort on substrate mixes. Once
the ideal size and texture is achieved, the differences start becoming
too subtle for me.

Regarding your water, measuring your source water might have been more
useful than some tank water, due to the presence of materials which would
alter the tank water's parameters after a while. Your kH 8 is your
buffer (8 degrees, or 143ppm). This is high enough to make your tank's
pH quite stable (stability is desirable, but it makes the pH harder to
change too). Your gH 13 (230ppm of primarily calcium) is listed as
fairly hard by http://faq.thekrib.com/begin-chem.html#reference . If I
reverse engineer your numbers, your pH is around 7.8, a bit high for some
applications but still very manageable. I've grown many plants in much
harder and more alkaline water, so while it isn't ideal, it is not too
far off the mark for low effort, if your expectations aren't too high.

I don't have any tanks running your parameters (I have some much higher
and much lower), so I can't speak from personal advice. I think you're a
good candidate for CO2 injection (if you decide to go that way), but the
effects will not be as dramatic as if the water had been softer to start
with. Some people soften their water by diluting it with RO, DI or
rainwater, but this adds a level of maintenance which some people find
excessive. In your conditions, very high light and no CO2 would be a
formula for algae, so I recommend that if not using CO2, keep your light
level under 3wpg. If using CO2, you will probably find dual DIYs or
pressurized will work best.

Some helpful articles here : http://www.csd.net/~cgadd/aqua/articles.htm
and I have many more sites bookmarked. I don't know how interested you
are in researching this to death (and I wouldn't). I'm no expert but
there isn't necessarily a 'right' way to do it anyways. If you want an
underwater garden au-naturel and are willing to wait for it, then start
the tank with a variety of plants and take it from there. If you want
more instant gratification, then get that CO2 bubbling and sharpen some
scissors ). Either way, some plants will not do well, and that's
perfectly normal. I hope what my answers lacked in accuracy, I've made
up for in perspective ;~).
