Benefits of Air Stones and A little of its Drawbacks


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. You can check the coolest designs and latest models of kids aquariums at KidsAquariums.com that will definitely suit your child’s taste.

The Fish


I caught a tremendous fish
and held him beside the boat
half out of water, with my hook
fast in a corner of his mouth.

He didn’t fight.
He hadn’t fought at all.
He hung a grunting weight,
battered and venerable
and homely. Here and there
his brown skin hung in strips
like ancient wallpaper,
and its pattern of darker brown
was like wallpaper:
shapes like full-blown roses
stained and lost through age.

He was speckled and barnacles,
fine rosettes of lime,
and infested
with tiny white sea-lice,
and underneath two or three
rags of green weed hung down.
While his gills were breathing in
the terrible oxygen
–the frightening gills,
fresh and crisp with blood,
that can cut so badly–

I thought of the coarse white flesh
packed in like feathers,
the big bones and the little bones,
the dramatic reds and blacks
of his shiny entrails,
and the pink swim-bladder
like a big peony.

I looked into his eyes
which were far larger than mine
but shallower, and yellowed,
the irises backed and packed
with tarnished tinfoil
seen through the lenses
of old scratched isinglass.
They shifted a little, but not
to return my stare.

–It was more like the tipping
of an object toward the light.
I admired his sullen face,
the mechanism of his jaw,
and then I saw
that from his lower lip
–if you could call it a lip
grim, wet, and weapon like,
hung five old pieces of fish-line,
or four and a wire leader
with the swivel still attached,
with all their five big hooks
grown firmly in his mouth.

A green line, frayed at the end
where he broke it, two heavier lines,
and a fine black thread
still crimped from the strain and snap
when it broke and he got away.
Like medals with their ribbons
frayed and wavering,
a five-haired beard of wisdom
trailing from his aching jaw.

I stared and stared
and victory filled up
the little rented boat,
from the pool of bilge
where oil had spread a rainbow
around the rusted engine
to the baler rusted orange,
the sun-cracked thwarts,
the oarlocks on their strings,
the gunnels–until everything
was rainbow, rainbow, rainbow!
And I let the fish go.

A Fish’s Bowl Is His Castle


Hamish, the fish, lived in a round fishbowl made of beautiful, clear, crystal. It was always sparkling clean. Inside the bowl was a gray, stone castle. It had a drawbridge, several windows, and if you looked real close, you could see gargoyles on the castle walls. Next to the castle was a rather large stone. It was brown with little silvery speckles in it. Some blue-marbled pebbles lined the bottom of the bowl and the castle stood on them.

Hamish loved his fish bowl. He was happy swimming around in it, going through the front door of the castle and coming out the back. He loved swirling around and around the large stone. Sometimes he’d swim up and put his face right up to the glass to look out and see what was going on around him. The curved bowl made his eyes look huge and googley.

Christmas was coming soon. Hamish could tell. Across from his bowl stood a tree, decorated from top to bottom with red, gold and green ornaments. He could see the reflection of his bowl in a gold one. Once he wiggled his tail back and forth and saw it in the ornament. He blew bubbles and laughed. Hamish wanted to put Christmas decorations in his castle.

One day, when nobody was in the house, Hamish took a big mouthful of water. He swam over to the edge of his bowl and used his fins to lean against it. He spit the water at one of the ornaments on the big tree. The red ornament fell off the branch and landed right in his glass bowl. Slowly, it sank to the bottom. Hamish smiled.

Using his fins, he rolled the ornament into the castle. It took up a lot of space, but Hamish didn’t mind. He swam around the red glass ball, looking at his reflection. He had so much fun with it that he wanted another one.

He swam over to the edge of the glass bowl and gulped a mouthful of water. He spit at the tree and knocked a green ornament off the branch. It tumbled into his bowl and sank slowly to the bottom. Hamish pushed it into his castle, using his tail. Now it was very crowded in there. He didn’t have enough room to swim in and out of the arched doorway anymore, but he had so much fun looking at himself in the glass balls that he didn’t care.

One more, thought Hamish. He wanted one more ornament. He filled his mouth with water, swam over to the side of his bowl, pulled himself up with his fins and spit the water at a gold ornament. It fell from the branch and landed with a soft plop, right in his bowl. It filled with water and sank to the bottom. Hamish looked at the gold ball. There was no more room in his castle. He would have to leave it sitting on the blue-marbled pebbles.

The crystal fishbowl was crowded. He didn’t have room to swim at all anymore. He had to stay in one place all the time, right next to the large stone. After a while, Hamish tired of looking at his face, fin, and tail’s reflections in the balls. He wanted them out of his fishbowl. He didn’t want to have any Christmas decorates in there any longer.

He tried to lift the gold ball up, but it was full of water and wouldn’t budge. He tried to push the green ball out of the castle, but the gold ball was in the way and it wouldn’t move either. Hamish didn’t know what to do. All he wanted was his castle back the way it was, empty and clear, so he could swim around like he used to.

Later that day, the little girl who lived in the house came to look at the Christmas tree. Since Hamish’s bowl was so crystal clear, she was able to see inside of it. “How did those ornaments get in there?” she wondered. She stuck her hand in the bowl and pulled out the gold ball. She dumped the water out of it and put it back on the tree. Hamish was happier. He swam around in the bowl. Next, she reached in and lifted the castle out of the water. The two ornaments were still inside of it. The girl dumped the water out and pulled the red ball and green ball from the castle. She then put it back in the fishbowl.

At last Hamish’s bowl was like it used to be. He swam inside the castle and out the other side. He did this over and over again. He swam around the large stone and blew lots of happy bubbles. From then on, Hamish was content to admire the colorful ornaments from inside his bowl and leave them on the tree where they belonged.
