There's nothing nicer, in my opinion, than water movement in an aquarium. This can easily be created by using a small air pump and an air stone. Air stones are made from some sort of porous rock substance. They feel like they might crumble in your fingers but they are quite tough. They come in all different shapes and sizes. The one I'm using in my tank is the Aquafizz Airstone by Elite. Its approximately 10cm long and I got it from Pets at Home for roughly £2.00. It's a dark colour and I cant make out if its black or dark green. You can get them in a bright blue colour but I think these are harder to disguise. Air stones have a duel purpose. Not only do they create very pretty bubble movement in the water, they also increase surface agitation, accelerates oxygen and help to release carbon dioxide build up. I use my airstone to create a small but effective bubble wall at the back of the tank. To do this you need some standard aquarium tubing and an air pump ( previous review). You attach the airstone to one end of the tube using the little plastic connecter that is attached to the air atone and the other end to the air pump. I then bury the airstone under the gravel in the tank, I hate seeing the airstone so I like to disguise it. When the air pump is turned on the stone will diffuse the air in all directions creating a lovely bubble display. This looks lovely especially when the aquarium light is on, it reflects the bubbles and really enhances your tank. The fish seem to like it too. If you want a large bubble display you will need a stronger air pump, and of course your display will depend on the shape of the stone you buy. If you buy a small one you will get just one stream of bubbles. This can look as attractive as a large display. I would recommend the Elite Airstone range, they don't last forever and will need replacing every so often but as they are not overly expensive this isn't a problem. Apart from being beneficial to your fish they do help to create a lovely underwater display.
I am not very much of a people person, I love animals and my pets are hugely important to me. I prefer the little cute fluffy pets, but my other half is a keen fish-keeper, and used to breed them as well. Since we moved in together he's introduced me to keeping fish as pets and I now have my very own fish tank! I have a Pets at Home store within only a 10 minute walk of my house, so this is usually my first choice for pet products. This air stone can be bought from the brick and mortar stores, or online at www.petsathome.com for just 99p. Pets at Home say: "The Long Air stone 4inch by Elite is an air stone that is great for increasing water surface agitation and increasing the oxygen content of aquarium water. This air diffuser creates a stream of bubbles that is great for creating attractive displays in the aquarium. Simply attach air stones to air pump tubing to create a line of oxygen increasing bubbles." The aquarium set up I have is a simple hexagonal column tank, which has been set up to create the correct environment for keeping tropical fish. I have limited it to keeping a small number of fish, so they can get the most out of their space within the tank and I currently have a Siamese fighting fish, two marble angelfish and four little bandit corydoras. After introducing the fish to the tank we soon noticed that the fish seemed to be travelling to the surface of the tank to take in their air, and that it was not very well distributed through the water. Luckily my boyfriend knew just what to do and we bought this Hagen Elite Aqua Fizzzz air stone to rectify the problem. It measures in at 4" / 10cm long and is a simple flat-ish tube shape. The directions were stated clearly and it was easy to set up within the tank. Installation: 1. Attach air hose to an air stone inlet. 2. Place in desired position in aquarium. 3. Weight air stone down or cover with gravel if required. 4. Adjust air flow as required. 5. Never restrict air flow from any air pump. In just a matter of minutes the air stone was secured at the base of the tank and ready to be used. The purpose of an air stone is to create bubbles of air through the water which will then rise up and disperse throughout the tank. Its main purpose is to aerate the water within the aquarium and allow it to circulate, but as an added bonus they are also a decorative item. My air stone is set in place in front of a large slab of slate that covers the back panel of the aquarium, and the bubbles rising in front of the stone create a lovely visual effect. Aqua Fizzzz air stones are available in a variety of shapes and sizes, but this 4" one is best suited to the size of my aquarium. Due to the properties of the materials that the air stone is made of, they may break or crumble if you remove them from water or if they are knocked enough to sustain damage while in the tank. My fish have left it alone and it is wearing well, without showing any signs of deterioration. The air stone has done its job well and we noticed a positive improvement in the tank environment almost straight away. I am really happy with how it has worked and it looks really great as well, providing an interesting backdrop to the scenery. It was an excellent buy, and at only 99p I would certainly purchase this type of equipment again. A real bargain that gets the job done and looks good while doing it.
I have used HAGEN'S AQUAFIZ AIRSTONES for over twenty years. They are cheap and easily available from most local fish shops. I has been my experience that once you take them out of the water they will NOT work as well as before. I always change the small ones from the uplifts every two or three months. The longer 6 inch,9 inch and the 12 inch should always be left in the tank when doing your manitenance. The sand stone type material will crumble if you remove from the water so they are better left in the tank. The small inch stones are great for the uplifts and placing inside ornaments or bogwood. The longer ones should be placed in the back of the tank. Small stones will work with most air pumps,but the ponger ones will need that extra bit of presure to work properly
