Tank is the most basic and important element in building an aquarium. First of all, decide the number of fish you want to keep in your tank. Also, see that the size of the fish is fine and if it can sustain in that particular size fish tank.

Try to avoid buying a globe tank as much as possible, until you need to keep one or two fish. A rectangle-shaped aquarium is always much better because of various reasons.

Buy a professionally set aquarium tank or get a ready-made plastic model through distributors. You can also approach mold-extrusion manufacturers to put your aquarium tank together yourself.

After setting up the fish tank, find a perfect spot that is draft-free and has a moderate amount of light for at least 8-10 hrs. Make sure to never place the tank in direct sun as that will heat up the tank water causing fish a discomfort. This is for the safety of the tank as well as the inhabitants.

Also, choose a location that does not have any problem with water spillage. Choose to place the fish tank at a convenient height, where it need not be moved. Then add the sand, bulk aquarium gravel or pebbles that are not too large, neither too fine in size.

After adding bulk aquarium gravel and other settlements, add conditioned water that is chlorine, dirt, excess hardness, excess acidity, or excess alkalinity free.

Still in case you think there is a requirement for temperature drop, then the maximum you can do is 2-6 degrees. In fact, adding bulk aquarium gravel also helps the temperature to cool down.

The warmer the water, the less dissolved oxygen (DO) it will hold. Here are a few tips that help in keeping the aquarium water cool and helps your little friends to survive longer.

  • If you have a fish tank with a top airtight cover, then open the covers and place nylon netting over the openings to prevent fish from jumping out. This process allows heat to escape. You can also direct the air-flow of a small fan across the top of the tank to lower the temperature.
  • If you have a window or any other place which allows direct sunlight in your room then close them immediately. This is because even indirect sunlight raises the room temperature by a degree or two, and every little bit helps.
  • If you have an aquarium light in the fish tank, then reducing its timing would contribute to reducing the water temperature. But it is also suggested to not leave the lights off all the time either as that's bad for your fish too. Though, it might not stand a chance if you have a freshwater planted aquarium. This is because it requires at least 8 hours of light per day. Therefore, you may have no choice but to buy an air conditioner or a chiller to solve your heat problem.
  • You can also aerate your aquarium tanks with a strong air pump to increase the exchange of gases at the water surface. This also helps in raising the level of dissolved oxygen.
