Actually, the bottles are in a bucket of water with a heater in it. The biggest heater that will fit is a 50W, and I have a digital thermometer in there too. Keeps it at 89 degrees, and the heater is turned up all the way. Currently getting 1 bubble every 3-4 seconds. And no bubbles in the tank.

As for pressurized, I could get a 10lb and use a manifold to split it between the 29G and 10G at one place, and the 5lb on the 10G at the other end. The problem is that half way between is where my gas fireplace is, lol.

Ouch. Yeah, it might be a better option to have one tank, regulator, and manifold for each set of tanks. Perhaps not as cost effective, but it will give you more flexibility with the placement of your tanks.

Weird you can't get your DIY CO2 to work. Only one time I've failed and that's because the yeast was really old. Have you tried just putting the yeast in a small cup with a little sugar to "kick start" it? I do that to every bottle I make.

I have a jello CO2 set up right now that's been running for two weeks and still going strong. About 2-3 bubbles every five seconds.

I know, it's really weird, lol... and I've tried about 10 times now, doing something different each time. Maybe I need a bigger heater to warm it up a little more. When I got home last night it was only 85 degreees.

But also looking into the Manifold option for my 2 pressurized bottles.

Heck I don't even heat mine. It just sits at room temp that ranges from 72-78 degrees.

Pressurized is the way to go unless you have multiple tanks. Then it gets a bit tricky. I'm going that direction by the end of the year for my larger tank that will be set up by then.

Not to Hijack your thread LWB, but my DIY seems to be producing a little too much CO2. I'm reading PH of 6.8 and KH of 6¬į. I don't know if I should be concerned or attribute it to the fact that I have only 4 plants in there with 2 new CO2 bottles that I filled yesterday. With a CO2 level of 29 ppm, it does seem kinda close to the "good" line.

EDIT: Also I just realized I got the Fleichels (sp?) highly active yeast instead of the normal stuff.

thats right where you want it Alshain. Infact a little more would even be better as that amount will start to lower towards the end of the mixture's life.

People have their CO2 in the range of 50ppm without any problems. The general concensus is that you want your CO2 at 30ppm to rule it out as a problem. Also note, CO2 only really becomes lethal to fish in the 100ppm range.

Well thats good, Chuck's calculator said it was in the high range so I wasn't sure. I'm still fishless cycling so I won't have any fish in there for a little while.

I leave mine at room temperature which right now isn't even 75 and they are pumping out like mad, amost the best i have had for a while as far as consitency. I think you might be running them too warm and bruning them out too fast.

A couple things I would try. First, lower the temp to about 75. Second, try less yeast to start with. Third, setup a control bottle setup with tap water at the exact same conditions as the one you make with tap water. If the tap water peeters out early then you could have your culprit! Try the same with the control with temperature and all tap water, one aty room temp and one with a heater.

Actually I solved my problems.... lol.

I bought 2 3-way manifolds with bubble counters for my pressurized system. So each tank will have it's own line, and will have room for 2 more planted tanks if I wanted, lol.

I also got 2 Reactor 1000's, one for my 29G and one for my 75G. Will be hooked up to my XP2 and XP3. And I'll have a line going from the vent on the Reactor 1000 to the aerator input on one of my MaxiJet 600's. It's going to be the ultimate setup, lol.
