6) Dissolution Methods
An effective method of introducing CO2 into your tank is required. If CO2 bubbles are reaching the surface of the water in your aquarium, then much of it is being lost and you are not getting CO2 dissolved into your water column.
There are various pieces of equipment (listed below) that will help aid in diffusing CO2 into the water. They all aid in the dissolution of CO2 to differing degrees. Whether you use one or not is not important; the important point is being able to get CO2 into your water.
From my previous article, I will just copy/paste the various methods of getting CO2 into your water:
1) Bell Diffuser: A passive method of CO2 diffusion, this relies on the assumption that CO2 will dissolve into the water column faster than the CO2 is produced (not likely). Not an effective method of introducing CO2 into the aquarium.
2) Feeding the CO2 tube into a filter intake: Slightly more efficient, this method allows the CO2 bubbles to be fed into the intake of a filter, allowing the bubbles to be chopped up by the filter impeller. Be warned that this method is said to shorten the lifespan of the filter impeller.
3) Commercially available "bubble ladders": Hagen makes a product that is known as "bubble ladder". This product allows CO2 bubbles to travel a long a track, allowing the CO2 more time to dissolve into the water column. The ladder is quite large and bulky (in my opinion), and some people may find it aesthetically unpleasing.
4) Ceramic disc diffuser: Typically a glass diffuser that contains a ceramic disc with miniature pores. These diffusers were first made by ADA (Aqua Design Amano). Such diffusers rely on the small pores on the ceramic disc to adequately create mini-CO2 bubbles, vastly increasing the rate of CO2 dissolution in water.
5) Inline CO2 reactor: Most arguably the best method of CO2 dissolution, the inline CO2 reactor is inline with a (canister) filter output. Using this method, the CO2 is very effectively dissolved.
