co2

[david13latham]

I want to add a DIY c02 system to my tank. I was just going to make a 3 liter coke bottle into a diy co2, but i have a few questions.

I would like to have the 3 liter for the co2 reaction and then going into a 2 liter in case of an overflow and then into the tank. Possibly doubling that up with 2 of the 3 liter reactors going to 1 (2) liter then into the tank. Most likely will make some sort of dome so it will dissolve.

Any mixtures i can use as a guide line?
Do you think this will be enough co2 for a 75 gallon, well planted tank, community?
Any suggestions on the dissolving in the water issue?

your not going to get the levels you need. even with 2-3 diy co2 bottles. save up and get a pressurized co2 bottle.

i have a co2 bottle a 20oz one that is not in use anymore and its just laying around. Would this be applicable?

you would have to buy a regulator. its best to spend the money on a real regulator and real co2 bottle 5 pound or more.

Okay...thank you, how long would a 5lb tank last me?

if you shut it off at night a year or so 24/7 6 months or so. then you just fill it up. with diy you would be making up new bottles every week and over time will run more money.

its true, and it cost about 3 bucks to fill a 9once Co2 tank so expect around 15-20 bucks for a 5pound Co2 tank, but make sure that its for Co2 and not Air

I agree - I'm using a pair of 4L jugs for a 46g tank - it's barely enough CO2.

Hard to say. I have a 100gal, and I use to have a 10lb CO2 cylinder (I now have a 20lb) and it would last me about 5 months. I do have a jungle in my tank though. Depending on your amount of plants and how much light you have --My quess is about 3-5 months with a 5lb.

for the most part its even cheaper then that to refill.

i would say for the most part 6 months is a average but not always a given.
