Precisely how effective are those small bubbles which come out from air stones, or diffusers? A number of aquarists believe that they perform a crucial role inside the aquariums with regards to oxygenation and air diffusion of the water, and that this air source is sufficient. When it comes to the rise of DO (dissolved oxygen) in a fish tank, the water surface is one of the main sites where this exchange takes place. Oxygen is blended down into the water; carbon dioxide is released out to the air, not forgetting that other gases readily pass through the permeable surface of water at the same time. This is the principle which our bodies work on whenever we breathe; inhale good air and exhale bad air. It’s the same manner with the fish tank.
So, if the water surface area of your aquarium is where the primary exchange of gases occurs, then why use air stones and also have bubbles in the aquarium in any respect? For the reason that they do have their benefits.
- They are widely used to drive various kinds of filters and equipment, for instance under gravel filters and a few sorts of protein skimmers.
- Fish tanks that contain solid covers or close fitted hoods on top are prime candidates for stagnant air, low oxygen levels, and high levels of carbon dioxide. Nonetheless, for these types of set ups with an under gravel filter run by an air pump, the fresh air bubbles that come up through the uplift tubes help to get rid of these problems by provided superb oxygen along with other gas exchange opportunities. A power head works extremely well instead of the air pump and stones to work the under gravel filter, however, if the power head is not equipped with an aeration function, or this characteristic is not used, it can provide low oxygen and low PH.
- Whether having an under gravel filter or not, air bubbles aid to maneuver the tank water vertically on the way to the surface, aiding with oxygen and other gas exchanges.
- They are an affordable way to move the tank water vertically.
- They do develop a wall of bubbles that can look pretty cool in the aquarium, plus watching them can be quite soothing.
Air stones can be made of ceramic, glass, or getting more in fashion, wood. Wood stones can be easily made at home with different kinds of woods that are attainable, however the most typical wood used is lime wood. This kind of air stone must be perfect for air driven protein skimmers, and they are reasonably priced to produce. These air stones are also available on the market.
Ok, so air stones do have some positive aspects, however are there any down sides with their use? Of course!
- They usually are not as reliable as power heads, water pumps, and/or protein skimmers are in making water movements within the aquarium. Most of these are far better at helping with oxygen and also other gas exchanges at the water’s surface.
- They do not move water swiftly enough or in adequate volume for what a tank normally needs for good at all times, vertical and horizontal, water flow. This condition can also contribute to a low or too little GPH (gallon per hour) tank water turnover time.
- They generate a lot of salt spray that in turn contributes to salt creep issues.
- They clog up.
- They tire out very quickly, in most cases need replacement.
- They can result in irregular air flow.
- Air line hoses can get pinched or kinked, which often weakens or cuts off the air flow.
- More often than not the air pump chosen to work air stones is inadequate, contributing to low air flow pressure.
- Some air flow pressure is dropped the longer the distance the air has to travel through the clear tubing from the air pump to the air stones.
- The deeper the fish tank water, the farther the air has to be pushed downhill to reach the air stones, resulting in shortage of air flow pressure.
Now that you have known all the benefits of air stones as well as some of its negative sides, you will be able to set up your aquarium completely. Kids can participate in this one of a kind hobby and might have their own fish tank if they want.
