11 Step DIY CO2 Reactor.

However you do it the co2 doesn't come out that fast so my Rena canister doesn't lose prime.

Co2 will really drop the pH fast, so expect this. I don't remember the formula for using pH and kH, but this is very usefull to know.

Okay, well I have aragonite sand, so hopefully that will help keep the pH some what stable right?

yes...

Maybe when you get yours all up and running it'll encourage me to hook mine back up. Like I said, the co2 kept rotting away the plastic on the water jug caps. I have to find another container and cap. I'm lazy

For years I grew plants just fine without co2 and expensive lights. As soon as I upgraded it became complicated. I'd like to hear about how your dwarf hairgrass id growing like a feild, or how the baby tears are growing like a carpet.

Maybe that will get me back into it.

i have a question about this, i had an idea i have a spare spray bar sitting around and i siliconed a bubble wand inside it so that nothing can escape out of the end and connected a T valve to the end now i plan on hooking a air pump up to 1 side and Co2 generator to the other use suction cups to secure the spray bar to the back wall of my aquarium under the intake of the power head that power my UGJ so some of it would be sucked into the power head forced through it turned into "micro bubbles" and forced through my jet system and some would also be sucked into the intakes of my canister and HOB filters, have the same effect that you had with yours Pete. and then having the air pump hooked up to the same apparatus i would be putting oxygen into the water at the same time. Helping to prevent any Co2 poisoning that might happen at night.

Think this might work?

Ummmm. A bubble wand inside a spray bar? I can't picture it. You have a undergravel jet system? I'd just run the co2 into the UGJ system pump, and like Gumbii said the impeller will do a lot to get it in the water.

I can't get what you're thinking. Maybe???

I'm not an expert on this, but I think you'll need a way to measure the co2. There's a way with using the pH and the kH but it only works if there are no buffers used in the water. I'd sign on to www.plantgeek.com and join their forum. They can help you with these specifics.

I'd keep track of the amount of yeast used as this will regulate the rate the co2 is generated. I'd start with 1 teaspoon. I don't think the sugar is a big deal. I used about 4-6 cups.

um...

i would... um...

dude that's a toughie... i wouldn't put it directly on the powerhead's venturi pump because it will create a huge vacuum... maybe you could have it close enough that the bubble gets sucked into the system, allowing it to get chopped up... i think it will work very well thru the UGJ system...

i would sans the entire bubble want spray bar apparattus... lol...

it's just too much hardware in the tank... just have the hose really close to the intake of the power head... by having micro bubbles going thru the undergravel jets should be enough for the co2 to get around...
