I got this co2 system from Petsmart today and was wondering if anyone knew if it is a good product? Its called Hydor co2 green NRG Natural.

I"ve never heard of that one before. It must be a new product. Does it involve mixing little packets of some sort?

It appears to be a fermentation type co2 system.

Ya it comes with 3 packets fo stuff you have to mix together and add sugar and water. It says that it works for 45 days. That was my next question does anyone know were I could get refills for it?

I do DIY also, and I go to a store in Columbia near my job that sells beer and wine making supplies and buy dry wine yeast for about 85 cents a packet. The one I use has a higher alcohol tolerance than regular bread yeast and can tolerate cooler temperatures also. Plus it's bottom flocculant.

Jiga, you don't really need to buy Hydro refills. All that's in the packets is yeast and baking soda. You can do as Joe suggested and get the more alcohol resistant yeast, as it'll make your solution last longer, or if you don't mind changing it out a bit more, you can buy a jar of yeast, box of baking soda, and bag of sugar for next to nothing at the grocer, and be set for years. The hardest part is figuring out how much of each to use, but if you go by the amounts in the packets Hydor uses, it should be pretty easy to guestimate.

Ya that sounds like a good idea. I found that you can get the refills fairly cheap about 11 bucks for a 5 month supply. I just haven't been able to find reviews on the product to know if its worth keeping or if i should return it.

I think this system will work well in my tank because it comes with a pretty nice diffuser with I read works well with low flow tanks. The initial cost is about 34 bucks and then 11 bucks every 4 months after that. Good for beginners I think. Now all I have to do is decide what substrate I want and wait for my plants to come and I'll be all set

If you like it and want it, you should keep it. But you can very easily get more information about DIY CO2 by checking other forums such as "the planted tank" or the APC forum. They even have stickies on the subject. Also, there is an amazing paper on it by John Levasseur called "A Treatise on DIY CO2 Systems for Freshwater-Planted Aquaria." It's an amazing paper. The only reason I recommend this other approach is that it is (1) cheaper, and (2) if you're inclined to DIY, it can be a source of personal satisfaction. It's very easy to do actually. Best of luck to you, however you do it. Regards, Joe
