Co2

[RedShark]

I have a 30 gallon planted tank.
For C02 i use the nutrafin ladder, but its for a 20 gallon tank and its not supplying my tank with quite enough.
I use Dry fertilizers.
I have 3.2 wpg with my 96 watt bulb.
I havent had algea probs in the longest time and am interested in providing my aquarium with more C02 for optimum results.
What do you guys think? Is it even worth trying?
Since dollar problems have risen, this is a chance to work on my resourceful savyness
BUT, I cant find the DIY Co2 from a soda bottle on the site... Can someone help a fella fish hobbyist out???
It will be greatly appreciated.

Here is what he gave me. I was actually using it on my 90g... I forgot how long ago it was that I asked. It's very easy to make, you will but need a different recipe for a tank that size.

I set-up a DIY CO2 rig at the weekend for a friend with a 70 Gallon and he is getting 30ppm!!

The whole lot cost less than £5 ($10).

You want to know how right?

You need -

2 litre plastic fizzy drink bottle with cap
Silicon sealant
6mm drill or similar
3 metre silicon airline/tubing
lots of sugar
dried yeast
bi-carbonate of soda
teaspoon
funnel
weighing scales
measuring jug
water

1. Drill 6mm or slightly less in bottle cap.
2. Insert airline an inch or so in hole and seal with sealant.
3. Allow to dry.
4. Recipe - 400 grams sugar, 2 level teaspoons yeast, 4 level teaspoon bi-carb, 1.6 litre tepid water.
Pour in sugar, add yeast, add bi-carb, add tepid water. Use funnel if necessary (less mess).
5. Attach airline to your Nutrafin diffuser.
6. Watch CO2 bubble away after a few minutes.

This mixture should give a fairly constant output for approx 7 to 10 days.

You could obviously make 2 or bottles up and couple the airlines to the same diffuser using a 2-way splitter.

Good luck.

As written by Pseud, please find THESE instructions.

I note that he has something here that the other method doesnt mention - check valves. 3 is a little over kill, you will get away with one on the main line, but the check valve is important if you plant on having the bottle sitting under a table/cabinet for example - stops water being siphoned out.
