Would the co2 escaping fromt he airlock on my homebrewery be suitable for CO2 injection in my fish tnak or is this just too good to be true. So much CO2 and it is just going to waste. *Sigh*

How are you going to make a secure connection between the water trap and your fish tank?
If you brew in the normal 5 gallons, then the amount of CO2 would be much too much, and you will kill your fish.
Wine will ferment slower. What do you ferment?
It could screw things up. If you slow down the rate of CO2 using aneedle valve you might ruin the brew. Plus I don't know how many alcohol fumes also escape. Hic....

Technically yes it is just CO2 that would work. But, you would problems with the rate of flow from Homebrew. In my homebrew there is a huge spike for a few days and then it tapers off. For an aquarium you want/need a steady stream of CO2. If it goes to high it can force the Ph down and the oxygen level down and kill your fish. Its really not that difficult to make your own DIY CO2 specifically for your tank......search on these boards for DIY CO2 or PM me and I will send you my "recipe".

TKOS- First, with any yeast/sugar CO2 generator your making alcohol, so the fumes should not be an issue.
Second, on the needle valve. The whole might explode if you valve it off without some sort of place for the CO2 to go. I do know someone who put a shutoff valve inline on his DIY CO2 to valve it off at night. He put a t-fitting just before the shutoff valve and put a large balloon on the side of the "t" so it would fill with CO2 at night and then i nthe morning when he opened the valve it would replenish the CO2 in a hurry. Two issues were, that the ph would swing quickly from the CO2 and it took forever for him ot get it all sealed up. Now, he just has an airstone on a timer that runs for like 3 hours at night. Second, he switched to a power reactor and the back pressure kept the balloon full of CO2 all the time.
