Well the video is up since yesterday Jan 30th 2010.
I added it as video response since I can’t post a video link into a comment, just click that or the annotation in the video.
You can also go through my channel if you like.
Enjoy
Precisely, 2 bottles, I will post the video today, hang in there my friend
so Dan,you are saying that to be on the safe side,we should use 2 bottles,1 for the mixture and the other one for the alcohol,so taht it can be prevented from entering the tank? plz help me,as i am BRAND NEW ZERO METER to this stuff =P
thankyou guyz! AweSomo84 & oBseSsloNPC
Thanks
I agree with you, but at the time I had no idea how to properly introduce the Co2 into the water, cheap but efficient.
I will post a vid soon, that shows how I did it a while back now, thx to my friends suggesting a couple things.
I should have the Vid up tomorrow, check it out if you like
Take care.
Hmm very professional man, I think your diffusion system could use a little work, but the alcohol chambers seem to be an interesting twist.
You are welcome and thx for the compliment, although this system is not my personal idea, I just put together tips from good friends.
And I can certainly do that for ya (put up another detailed video).
The quantities matter indeed.
The mixtures I used in the video, was a overkill to show the reaction quicker.
A proper mixture can take up to 15-24 hours to activate, which I did here in 15 minutes.
Read below for more good ideas, plus I will add these infos in the update.
Stay tuned
Oh yeah, I missed out on that one. Airstones start to disolve after a while.
Thanks mate!
and also add a note NOT TO USE A blue defuser and rether put it trough a small filter these bubbles are way to big to let the plants take up the co2 and the defuser will pulverize
just be save and turn the cap of the bottle so there will be no pressure build up ,… if there is to much co2 the water will geth sourer
peace and love
Dude change the discription and the amount of yeast you use in this video buy adding NOTES , your learning people the wrong shit!
You shlould just add a cleanning bottle between the diy co2 bottle and aquarium , do not keep your bottle that long it will just push in bad stuff than co2 .
hey man just get anubia’s fpr your cichlids and some other STRONG plants other ones they are probably take care off .
Make sure to geth the right dosis of yeast and not like my friend did here
dude,you are a genius !
excellent stuff! i am thinking to start soem plantation in my 70 gal tank(mainly cichlids)
man! i was lukin fo this kinda stuf! THANXX!
p.s when do we have to clean or refill the yeast bottle? can you please make a video explaining each and every stuff one more time?? :S (a request) so that i can clearly see one final time,and that does the quantity of sugar or yeast really matter for diff tank sizes?
m a bit anxious. =P
10 STARS!
As the yeast respires it produces co2 and alcohol, this alcohol is actually toxic to the yeast and will eventually kill it. Adding bicarbonate of soda (baking soda) will act as a buffer and stabiliser which will reduce the toxicity of the alcohol and keep the yeast respiring for longer. My mixture lasts for up to 4 weeks (2 litre bottle). Also, brown sugar seems to last longer than white cane sugar .
Good question, glad you ask.
As a matter of fact, I turned on the air pump, because that was easier than turning off the Co2
Because at night, the plants use up oxygen and produce Co2 themselves.
If you were to leave the Co2 on over night, your fish will be floating on the surface the very next morning or at least look like drunk, bad hangover and all.
But yeah, stopping the Co2 injection is a must at night!
So do you recommend disconnecting the bottle from the aquarium at night? or just leave it going?
Thanks!
Oh I see! Great idea! I have two tanks as well! Thanks!
Hey Shareallicu,
thanks for the comment
You can even use 1 small one or a big one, dont really matter.
All that matters that you clean it out once the Co2 stopped flowing.
I had 2 bottles because I wanted to supply 2 tanks with them, separately.
So 1 bottle filters for each tank kinda thing, but yeah, 1 big bottle will do just fine.
Hi thanks for the video, do you need two little bottles to filter the alcohol? or can you use one large one?
Hey “ali”, yes indeed, the small bottles have pur water in them, they serve as a “rough” filter.
During the process of sugar being transformed into Co2, you also get alcohol.
That is a part we dont want in the tank, plus a few bubbles of sugar-yeast-alcohol-mixture may travel through the hose.
If there was no inbetween filter, that stuff would end up in the tank.
Best regards, Dan
so all that’s in the small bottles is water? right
Wow, are you serious? Hehe, sounds like a nice meal for them bacterias
Keep the great tips coming mate
