Easy intro to CO2

The Bio CO2 set was my first attempt at using CO2 in a fish tank and it was very easy to install and start. All you need to do is add water to the main bottle with the gel, add the capsule of yeast (the capsule is in the top of the gel bottle) and wait for the yeast and sugar to react. It comes with a neat cardboard mount for the bottle and bubble counter that sticks to the side of the aquarium. To get the CO2 into the aquarium, this model comes with a little plastic part that goes before a filter's spray bar. It's supposed to go with a dennerle filter, but it does fit on the little zoo med canister filter I'm using on my tank. If you don't have a filter with a spray bar that you can fit the little connecter to, you'll need to buy a separate diffuser. Other than that, the CO2 part is amazing, and my plants have grown like crazy.
My favorite part about this is how low tech it is. It's just sugar-gel substance, yeast, plastic bottles and tubes. No need for electricity or other parts. It is hard to tell exactly how much CO2 is going into the tank, but the sparkling gouramis and small herd of ramshorns are doing well and haven't shown any signs of stress. The Bio CO2 system is an excellent introduction to CO2, especially for small tanks. It's also pretty gentle on your wallet. I think it is also a good way to jump-start a planted tank and grow in plants quickly.

Live Arrival Guarantee
We guarantee our live products will arrive alive. We ask that you do your part and minimize the amount of time our packages sit out in the elements. It can also be a good idea to avoid ordering live items during extreme temperatures. This would be when night time temps are below 35 and over 80 degrees during the day. Now these temps are not for sure death, it's just what makes it easiest for all of us during shipping.

When temperatures are cold we will use heat packs and extreme cold styrofoam liners. Shipping live goods is difficult as our warehouse could be 70 degrees and your home could be snowing, and all the stops in between. We do our best and will make it right for you and may request to try again at a different time.  During heat waves, it's best to avoid ordering live goods as ice packs etc don't do enough to mitigate it. 

30 Day Return Policy
Our goal is to provide a fair way to satisfy our customers and not lose money while doing it. We make every effort to fully disclose how our products work and what is to be expected. A damaged product during shipping is an automatic replacement from us. When it comes to a difference of opinion such as: "My fish doesn’t like this food." That we don’t refund for. However, if you decide the light you bought is a bit too green for your liking, provided it is in the original box, within 30 days and purchased from us, we will refund it at your cost of shipping.

If you would like to return a product, start the process by emailing us at shipping@aquariumcoop.com This allows us to see if there is something we can do before returning the product such as a feature you didn’t know about or send you a return label. We don’t require an RMA number, but do ask you to contact us to initiate the return. Please do not call the retail store as they operate separately from the warehouse and will not be able to issue you a return label etc.
