I setup my diy yeast / sugar on Friday afternoon using Flieshmann's quick rise yeast. 3/4 teaspoon in the mix (5 bottles) daisy chained on a gang valve.
Ok, no co2 production by Sunday night. I added warm water and more yeast. Still no production this morning. No leaks in the system. If I squeeze the bottle I get bubbles. The room temp is coolish as I've stopped heating so its in the range of 18 to 20 celsius. (turned the heat up this morning, heating at the end of April!!!!!!!!)

(f it hadn't been for my clutch repair on my 5 year old s.u.v. I'd be pressurized today :mad:)
 
Could you Yeast be bad?
I know the first batch I tried was with old yeast and nothing.
So I bought some new yeast and wooola co2…


On the side note…
5 bottles.... OMG..
well, Swimfins when they get going will they put too much CO2 in ur tank..???
i have a 72 gal and i am using only one bottle, I get about 3 bubble per sec.
I though that much CO@ plus my powered reactor (Tom Brar method) would be enough..

Last week I had PH 6.8 KH 6.5, CO2 was around 30ppm
 
I've never really gotten more than 30 to 32 ppm with the 5 bottles going. :thud:
I diffuse the co2 using a plastic spice bottle inverted and the tubing up into the middle of it. My spraybar passing through the bottle.

The yeast is good until 2006 or so it says. I dunno, its never really worked consistently for me on this tank. I can't seem to get enough pressure out of the bottles. They are placed beneath the tank itself. I just can't figure out why not. I think I'll just scrap it and go pressurized asap!

J/K, but pressurized really is the way to go. If you have multiple tanks, consider getting a larger (10-20#) CO2 tank and a CO2 manifold to split up the CO2 between your aquariums (so you don't have to buy multiple regulators and other CO2 accessories).
 
more connections = more leaks

I suggest going down to one bottle, then see if it works. The more connections you have the more chance for small leaks.

Also see that there is no water in the lines anywhere, the bottles can only move so much water and if any water got into the lines, that will take up the pressure generated. Often, just tpping the water out of the lines is enough to get it going well. I alway kept the bottle on top of the tank until it was flowing for that reason, a little CO2 in the line will actually suck up water as the water absorbs the CO2, then the line fills up.

Thanks anona, I've checked for water in the tube. I closed off all the valves, waited for the co2 to back up and then opened the valve one by one and poof, a big surge,

then a trickle, then nadda!

I'm about fed up with it all I've benn struggling with this all along and only got it going on 2 or three occasions and I can't figure out why. I've even dumped everything and started from scatch 2 or three times. It works fine on my 25g, but the big tank is a problem....weird isn't it?
 
Anyone who would not forgo a clutch repair for a CO2 tank is really not concerned about her plants in the first place. It is just that easy.
