You could experiment with a DIY system
to see what difference it makes before you spend a lot of $$ on a tank system.
I've been using a hagen ladder
for the co2 diffuser and it seems to work. The bubbles get smaller and smaller as they get to the top of the ladder. It takes awhile for the plastic to get waterlogged and work properly.
Hi Argus, I'm bit sceptical about DIY system since I'm new to this, and that would be another variable which I can do wrong. I'd rather go with a manufactured solution, and when I learn how this all works I might go with DIY. Also my tank is small (5g) and I home that it would not break the wallet.
What is the purpose of the bubble counter you mentioned above?
May I ask why you are wanting to supplement with CO2? Is it because of the plant type you want to use? You want fast growth? etc
With such a small body of water, I would normally suggest you deal with the carbon needs of the plants by either frequent water changes or keeping it low light and using something like Excel liquid.
If you do want to supplement, you can go DIY or a purchase small paintball canister CO2 kit like the one Fluval puts out.
Hi MiamiArt, well some of plants I have and would want to have are high light demanding, and also I would want to see results sooner
Also I think when plants grow to a certain level I would be able to reduce/remove the CO2 source when I would not need fast groth anymore. Is that correct? I'm already added daily doses of Excel, but there are some contradicting sources. Some of them say that Excel works and some say - doesn't.
Are you referring to following kits:
A CO2 system is tricky to set up and expensive to run. It's not worth the time and expense unless you're dedicated to keeping plants that demand strong lighting. A tiny tank like a 5G will be challenging enough just to keep the water clean enough to support even one fish.
You'll give yourself the best chance for success if you go with a larger tank, say 20 to 30 gallons and keep things simple by going with undemanding plants like Anubias, Java fern and Amazon swords. These need no special lighting and use the fertilizers the fish produce.
hi BBradbury, could you elaborate on this more? How is the CO2 related to water cleanness? I'm using a canister filter which seems to be able to clean the water fairly quickly at this point.
A diy setup can be time consuming and work especially if you do the yeast method of co2. Baking soda and citric acid or vinegar is a bit easier. That method creates co2 immediately. The easiest way is pressurized co2. A *single stage co2 regulator, a precise needle valve and a 10lb co2 tank plus a way to create and deliver teensy weensy bubbles into the water column. Some people use a piece of bamboo skewer stuck into the co2 delivery tube and into a Powerhead's water pump port. You could also use a co2 diffuser see Google Images
. Such a system even when left running all the time will last years with a 10 lb co2 tank on such a small tank. I use a 20 lb co2 tank system on my 47 gallon tank and it lasts for a few years. You do not need a solenoid on/off valve. Once I dial in the co2 that's it until I need to replace the co2 tank. My tank is very heavily planted.
*Victor CGA 320 regulator. Cost $90. Got it from a welding supply store. With a Fabco NV-55 needle valve http://www.fabco-air.com/products/fl.../NV-55-18.html
The easiest of all methods is the Diane Walstad method.
hi Steve. Well, that size of a CO2 tank would be overkill for my tiny aquarium, isn't it?
I've also noticed CO2 tablets in the market. Do they work? I'm just thinking to boost the plant growth for initial period and then will see how it works.
