Once your Aquario Neo DIY CO₂ Kit runs its course after 50 to 60 days and the underlying stabilizer gel is completely spent, you don't need to throw away your hardware or buy an entirely new system. The Aquario Neo CO₂ Refill Pack is an inexpensive, mess-free maintenance pouch designed to completely reset your original bottle. Packed with a fresh dose of specialized gel matrix powder and matching active bio-yeast packets, it brings your carbon injection system straight back to peak output so your planted aquascape never suffers from a sudden nutritional slump.

Reviews
"Probably not gonna get to use. System stopped producing gas or atleast enough pressure after a littler over a week and after two failed reset attempts at different working temps and several failed cleaning attempts on the ceramic disc have decided I waisted my time on this kit and got a actual co2 system. The idea is cool but it’s better to just spend the xtra money."
doesn't work
"i bought the neo co2 twice now, thinking the 1st time i was the reason it didn't work, this time I made sure I followed the instructions to the letter,, Still doesn't work. total waist of money"
Works great, love ordering from
"Works great, love ordering from Buce Plant."
Another happy purchase
"This is a great place to order from. They stand behind their sale including live items."
"A lot bigger than expected! I bought two thinking they were the mini packets that came with the original kit, it is in fact a quart sized package. Not a bad thing at all, but future buyers know you probably only need one ;)"
Received intact, setup was easy
"Received intact, setup was easy and it works perfectly. Thanks"
"Awesome as always"
The Aquaria Co2 system works
"The Aquaria Co2 system works great for a 5-8 gallon aquarium. I usually get about 3 months out of the refill, mostly because I'm lazy and don't worry that much about the checker being bright green. I find as long as it is greenish we are still good. Obviously your milage may vary. Good product at a reasonable price"
"Love it works awesome just like always"
Alternative that I like.
"Great product that doesn't rely on the pressurized cans . I was weary of those do to the reviews I have seen else where. The instructions were a little weird on box. They are on website so definitely follow those instead. Overall it has been doing good so far. I'd it does what I expect it to do I will change review."
