can you use the co2 given off by a homemade brew of beer?
Can you use the co2 given off by a homemade brew of beer for your CO2 supply for your fishtank or are there other gasses given off in the reaction that could hurt the fish?

Thank you for this description. I've been slow to get into CO2 for my planted tanks and I'm more confident with setting it up now.

Take a look at what people have said about the electronic regulators that Aquarium Plants.com produces:
Nowadays, it may not be possible to build a cheap (dual stage) system due to supply and demand, but when I built my setup, I managed to get everything (dual stage regulator, needle valve, solenoid, bubble counter, all fittings, and a 10 pound CO2 cylinder) for around $200, making this particular regulator not worth it.
That being said, you could purchase the cheapest single stage keg regulator that you can find and put a solenoid and needle valve on it, and call it a day too. Ultimately, it will achieve the same goal (namely, injecting CO2 into the aquarium).
What happens along the way (reliability, accuracy, whether or not it breaks down) are just additional things to consider that may increase the cost of a product in the end, so what you decide to purchase in the end depends on what you value the most.
The same goes for anything else (cars, electronics, clothing, etc). Why do some people buy a second hand car, while others purchase luxury sedans?

What am I missing here?
It is simple, it works, costs less and fails safe!
Maybe it is like the IPhone. The equipment used to make it is not worth the price of the phone but it is cool to have one.
I guess a really good regulator is not cool if it isn't the same old way.

I believe the general consensus was that having an entire system rely on a single point of failure was a bit unsettling. Furthermore, the equipment used itself was not worth $270.

It takes the place of all of these and only costs $270. I have had two for (I guess) 5 years and they are fantastic.

|burr740||Fair point. Yeah a rugf is what Im talking about. I just got to thinking about various scenarios. It would definitely require a certain kind of platform and a deep(?), fine gravel bed.|

Might be more hassle than it's worth, since generally RUGF plates are not used for fear of roots getting tangled.

I think it might work with a true undergravel filter if the co2 line was plumbed into the intake of the powerhead, or whatever pump was creating the downflow. Preferrably pre-diffused with a chopstick or airstone, etc. Because underneath the platform you'd have a wide body of water with decent circulation, under a certain degree of pressure.
Otherwise, what ^he said.
*Edit: Actually this might be a fantastic idea. Say you have a reactor already with near 100% dissolution. Instead of routing it to the tank via spray bar or whatever, pump it down through an undergravel filter, and let the CO2 enriched water seep up from the bottom to the top. Idk, just a thought...

|Darkblade48||The substrate would probably prevent the CO2 from coming out until it became a rather large bubble, at which point it would float to the surface, possibly moving your substrate at the same time.|

Very good write up and thanks for your hard work.
I have a question (it might be a stupid one but I am new-ish to co2) would there be any merit to diffusing co2 through the substrate using tubing arranged in a serpentine fashion (similar to under-gravel heaters) with small holes poked in it?
I'd imagine a medium sized gravel would work quite well to diffuse the bubbles and a more direct route to the plants as it diffuses out, the only possible problems I could foresee (and I might have just answered my own question) is the gas pressure would have to overcome the pressure from gravel or be trapped and/or it might build up and release large pockets all at once, also it seems there would be a high unpredictability factor.
