Nutafin Co2 Help!

[Lightning86]

Hey Guys!

I have a Nutrafin CO2 kit!
I was told not to use the packets that came with it and instead make my own mix up.
Been out today and bought Sugar and Yeast

Erm how much do I use?
it's one of these kits

Thanks!

Here's a basic guide to using the popular Nutrafin yeast-based CO2 units, based on my own experience.

1. Fill canister with regular granulated sugar to the first line.

2. Add 1/2 teaspoon of dried yeast (available from supermarket).

3. No need for "Stabiliser" unless you have v. soft tap water.

4. Top up to second line with tepid (approx 30C) tap water.

5. Stir.

6. Fix lid tightly.

7. Attach tubing tightly.

8. Watch the bubbles appear after 10 to 30 minutes.

Ambient temp. affects bubble rate, cold = less output, warm = more output.

More yeast = more CO2 for shorter time.
Less yeast = less CO2 for longer time.

1 teaspoon of yeast will give you around 30 bubbles per min. for about 7 days. This should be good for up to a 100 l. / 30 gal. tank.

Aim for 30ppm CO2. Change mixture regularly to avoid unstable/low CO2, this causes algae. Test for CO2 using pH and KH kits and this table - http/www.tropica.c...q...stic&id=445

Clean ladders may clog bubbles up for a while. The bubbles will run up smooth after a few hours or so.

Use multiple units for larger tanks. Change mixtures alternately for stable CO2.

Enjoy your plants!
