Defusing Diy Co2

[fish_keeper2]

i have been running diy co2 in my 29 gal planted tank. for some reason ive been running on the same mix now for 2 weeks.ive been shaking the mix every night and ive been getting lots of bubbles. anyway im not sure if its being defused in the water enough. ive only been using an airstone. any suggestion on how to difuse it better.

thanks. i keep mine on the other end of the tank from the filter. ill move it tonite.

my mix was only apporximate. i belive i used about 2 cups of sugar, 1/3 tsp of yeast and 1/3 tsp of baking powder and i fill the a 2 litter bottle 2/3 of the way with water. i shake it every night too.

I found out that using a airstone inside the intake tubing would reduce the noise since the bubbles are smaller that just being releasedby the tube.

fishkiller_nomore, this is the mix that I used and its going great (2 weeks & counting):
2 liter bottle
2 cups sugar
1/4 tbs yeast
1/3 tbs baking SODA not powder
Fill it up with water until it reaches where the top of the label is.

You don't have to worry about shaking it everynight. I don't know how to do this without getting yeast into the tubing(??) anyways. One big thing is to make sure the bottle is kept WARM. If you look at the thread I posted I have the bottle in a 1 gal specimen tank from Wal-Mart with a heater in it.

Before I started using the Nutrafin DIY/COS system I used the airstone method, then I was advised to try one of the hardwood 'airstones'.

I gave it a try and the bubbles were much finer than the normal airstone.

In addition to this I used a home made CO2 bell sitting above the bubble stream to capture the CO2. I made it by cutting the bottom off a 2Ltr soft drinks bottle and attached a sucker to it using silicone and them stuck this on the side of the tank about 5 inches above the bubble stream, this kept the CO2 in contact with the water for much longer.

Note: with my homemade CO2 bell, I split some airline tubing length ways and used this to line the edge of the bell where I had cut the bottle ... just to ensure there were no sharp edges for the fish. It was a little tricky to get on, but worked (and looked) fine when held in place with a bit of silicone.

I still have this home made system on standby. I would use it again, but the Nutrafin bubble ladder is giving me some great results at the moment.
