Lets talk DIY CO2 system...

I was wondering if there's alternatives to the 2 liter bottles most people used....any other containers that's more reliable or easier to work with? or 2 litter bottle's the best way to go...

and wats the "best" mixture? what ratio do you use for yours?
How many gal. can the diy handle? I am thinking about diy co2 for my 37 gal...do I need more than 1 ? or I can use a bigger container and just do it like that...

I've seen many ways of diy....does any of you tried different ways and which one's the best?

sorry i am just thinking about adding co2 to make my plants look better and am very new to co2 system...thank you for your info. and 2 cents.

ITS NEVER ENOUGH!!!

i just started to use glass jelly jar for my co2 with my 10 gall shrimp tank i just started. i wanted to use a jelly jar because it can hold more presher so i can use a glass diffuser iam still waiting for the glass diffuser in the mail.but i still used the regular 2 cups of sugar and about a quorter teaspoon of yeast and it is making about 20 bubbles per min in the glass jelly jar with a hole on top of the lid in the middle for the tube

2 liter bottle is the way to go because it can hold alot of pressure, it is designed to hold the
co2 from the soda. and also because the lid can be easily dilled to attach the tubing.

I'm using 3 bottles of apple juice , and i have no idea how many bubbles I'm getting per minute because they come out so fast that i cannot even count.

These are the bottles I'm using.

Do yourself a favor. Go to the search feature on the top right of this page, click advanced search and type DIY CO2 and search for "Search Titles only".

There are hundreds of threads on this topic and yet everyday I see a new one.

If you search google you'll find millions of combinations. I used to try and find one and my head spun.

I searched for DIY CO2 recipe and you get hundreds of combinations of sugar/yeast/water/temp .. I tried about 10 different ones.. they all seem to work.

In terms of containers..I've seen different combinations of:
Gatorade bottles
Pop Bottles
Large Costco sized Juice bottles etc..etc..

I've used all three and they all work pretty much the same. (at least for me)

You will also find that people will say that bottles will explode if you don't use the right plastic.. I've never had one explode on me.

I did DIY CO2 for about year on 2-3 tanks.. I got fed up and got pressurized.

But.. as long as you use a tried and tested recipe it should be ok. You'll have to adjust for the size of your container but it all works the same.

As for too much CO2 for your tank. It is pretty tough to have too much CO2 from a DIY system. It is MUCH more difficult to get a consistent rate of CO2. If you don't watch it.. you'll get BB Algae.

Oh as for running 2 bottles. You can run 2 inline bottles. I used to do that so that when one ran out I could change the other one and get a more consistent rate of CO2.

Just google |DIY Co2 recipe" you'll find tonnes of info.. Hope this helps

+1. The 1.89L juice bottles are much wider at the bottom and very hard to tip over. If you have cats or kids (both equally dangerous) 2L pop bottles are not the best option. The caps are nice and big on the juice bottles as well and a little easier to work with.

2 cups sugar
1/4 tsp. yeast
water to the shoulder of the bottle
