water and yeast CO2 mixture,video

Yes it's my own video,I done it primarily for the forum tbh so if there was any questions on it I could answer the here, it's so handy to do with the smart phone it's scarey!

Cheers john glad you like the idea.

Great vid thanks for posting, i always wondered how it was done
Do you get good results what do you use to get it into the tank plastic bottle, bubble ladder?


Mark

Have to say I get great results with this,I done this video to go with the other one but I had some editing issues,just in case anyone has trouble hearing what is being said cause the audio isn't great the mixture I'm using is 2 and 3/4 cups of sugar to 7 grams of yeast,make your sugar and water mixture with tepid water first and your yeast and water with slightly warmer water, when you pour your yeast on to your sugar and water mixture it should settle on top because of the temperature difference,as it equalises you get a slow and steady reaction which lasts quite a long timearound 2 to 3 weeks

Great idea making your own video for the site. Fair play to you for going to the trouble.

Thanks for the vid, looks a good idea, will give it a go the next time I`m home, keep the vids coming
Have you been using it long? have you had any problems with it? has it made much of a change to the plant growth in your tank?

Sorry for all the questions just interested

At the start I had some seal issues,this one is the second one I've done,I found that tech7 works the best as a seal because its slightly flexible when it cures,and you need to use very little, I get quite w good growth rate from my plants, mostly broad leaf stuff like swords also giant vallis,I get around two shoots coming up every 3 to 4 weeks. Also its important to remember that if your going to make a DIY set up you should use bottles that are designed to hold pressure,fizzy drink bottles, the other thing to remember is that if you open a bottle of fizzy drinks and leave it in the fridge that it goes flat, I'm nearly sure that there designed to do that so you go and buy more,bearing this in mind I use ptfe tape to keep the seal sound after a fresh mixture

@ anglecichlid
I was going to post similar thread when I found yours.

What you have shown here is very good cheap solution to keep your plants healthy.

I've been using this for years, until I brought to Ireland proper co2 bottle

Some smart people did lot of tests with yeasts, sugar and water, and they found out a system that works very well
it is called

"1410"

1 litre of water
400grams of sugar
10grams of yeasts.



You are using dried yeasts, but I recommend using fresh yeasts.
They can be found in every Polish shop in Ireland they are called "drozdze", Fresh yeasts "1410" produce more co2 and last for at least 3 weeks.

As you can see on the picture attached - one elastic tube is going from the mixture bootle to the bottom of 2nd bottle which is filled with clear water. 2nd elastic tube is going from the top of bootle with clear water to the aquarium.

tip
drill a hole in a bottle cap ( 1 in 1st, 2 in 2nd) 1mm smaller than tube diameter. put tube in and superglue it.

!! Warning !!
!! be careful !!

when mixture stop producing co2, or if by accident you shake bottle too much you can poison fish in your aquarium

to prevent this use small safety valve like this one below to prevent mixture suction ( connected between 2nd bottle and aquarium)



total cost
400g of sugar - 50 cents
100 gram of yeasts ( smallest available pack ) ~50 cent.

This set is for tanks up to 50 litres I'd say.
If you have bigger tank add more yeasts. but don't add all at one time.
wait for 12h and if you want more co2 bubbles, add more. ( it takes about 12h to have set fully working)

Cheers captainslow, to be honest I searched high and low for live yeast and the only place I got some was superquinn,
Over the counter at the bakery section,
But I have to say the fast action stuff is doing the biz at the minute,
But it's good to know where to get it again if I need it,
The other thing is with the fast action stuff you don't have to wait for 12 hours!
It starts producing almost immediately,
Plus with the way I have it mixed in the video its still producing,
That's over 3 weeks now!

Sorry it is my poor English - mixture start working instantly, but it gets proper full "power" after 12h.
You can get drozdze in a fridge section in these Polish shops. It look like a small butter - you need to cut it into small tiny pieces before adding to the bottle.

Just a quick note on disadvantage of this system - it works during the night as well, and as there is no light plants are not producing oxygen, and level of co2 is increasing in aquarium, what doesn't suit fish.
So to improve system you can also insert small valve into the tube and open it for the night time to let co2 go out to the room, not aquarium.

where did you this small valves ( bulkheads ) that are attached to the bottle caps?
i run diy co2 in my fishtank. co2 tube is attched to filter outflow in the place of airtube, air valve is being installed on the tube and im opening it for night so instead of co2 - o2 is being difused by filter.

do you get good results using this.can you compare it to easy carbo.i m thinking of getting the jbl bio 180

I use a combination of both,
The mixture can last between 2 or 3 weeks,
I can honestly say the diy CO2 has a huge effect on the plants
As mentioned above you can poison your fish
But it's never happened to me
Its great for lowering ph also and it does it quite slowly!

i add a little molasses as well. it's supposed to give the yeast a little more nourishment.

and according to tina turner, along with salt pork it's all you get in jail in Nutbush City Limits

and for any homebrewers out there, use juice in big fermenting buckets! although 400g per litre will give quite a strong "brew", bread yeasts die at 4% alcohol (approx) but it is possible to get a "turbo yeast" that brews to 21% alcohol and quickly - would be perfect for your set-ups and is available at "thehomebrewcompany.ie"
also maltodextrine and brew/beer enhancers, and yeast suppliments will help the brew. even if you don't drink the results this will all help your co2 production as more alcohol = more co2 by-product.

as for dried and fresh yeast - all you do is sprinkle dried yeast on the surface, let it soak for 10 mins then stir in. and any left over sludge in the bottom (leave brew to settle) can be re-used up to around 5 times as a starter for your next brew (co2) meaning less yeast need be added at the start. also i'd suggest having a couple of these on the go at once as fermentation can take a few days to start for the yeast to become active and reproduce - but bread yeast is defo not suitable to an extent there is too much sugar the bread yeast will die off at a certain alcohol level and there will be alot of sugar unfermented

hope this helps

thanks for that tip. makes alot of sense!
