Fish Tank Open Bottom

Simplified fish tank. Volume: Top tank 130 litres. Bottom tank 120 litres.

WHY AN OPEN BOTTOM TANK ?

Submersible biological filter in lower tank helps to maintain clear water. Water change and massive cleaning is minimized. Cleaning is also make simple. Partial change of water and removing of dirt particle, if require, is carried out in the lower tank that include feeding. All rocks and plants in top tank are placed 12cm above bottom tank to allow easy access should siphoning of dirt is needed. Rocks need not have to be removed while cleaning is in progress.
Water current in top tank is activated by air pump.
Fish able to move from bottom tank to top tank without restriction. Mini waterfall in lower tank is to provide extra oxygenation of the water.
The open bottom design allows replacement of plants and decoration as often as you like.

BUYING NEW FISH
Fish aren't exactly the expensive sort. They don't wag their tails or purr, so it's really hard to tell if and when they are happy or sad. But they do have feelings and can feel stressed, just like us. They also have likes and dislikes, and character traits of their own. And surely, they would wish to "live happily ever after" too!
So never buy a fish just because it strikes your fancy while you are out "window shopping" at the aquarium outlets. If you intend to acquire new fish for your aquarium, do a little of homework before you go shopping, so you can provide a suitable home for your new pet for all of its life.
Here are some questions you should ask when buying new fish:

HOW BIG WILL IT GROW?
Think long-term. Find out the approximate size the fish can be expected to eventually reach. Make sure you have a large enough tank for your fish to live comfortably in. Since a tank can support about one inch of fish per gallon, you wouln't want to keep a fish that might grow six inches long if you have a tiny tank! Lack of space could stunt it's growth and shorten its life unnecessarily.

WILL IT GET ALONG WTH THE OTHERS IN MY AQUARIUM?
Some fish are territorial and will not tolerate the presence of any other types of fish, and are best kept completely on their own.

IS MY AQUARIUM SETUP SUITABLE FOR IT?
Depending on the characteristics and habits of the fish you are eyeing, these are some of the things you have to consider:
If it's timid or reclusive fish, are there enough nooks and crannies for it to hide in? If it's a big fish, is there enough open space for it to swim in? Is the fish a voracious herbivore that will eat up your carefully planted aquascape?
The condition of water is important as well: Is the temperature range of the water acceptable to the fish? How effective is the filtration system? Is there any risk of upsetting the equilibrium of the aquarium if you add more fish to it?

WHAT DOES IT EAT?
Most aquarium fish eat flakes, but some like to have treats like freeze-dried worms, bugs, plants and even small animals in their diet. Find out what type of food your new fish likes to eat, so you can take home its favorites foods at the same time.
Don't treat fish as "disposable pets" and let your ignorance cause them to die a premature or painful death.

FILTERING SYSTEM
With a proper system, you can spend more time enjoying your set up and less time worrying about maintenance.
But the greatest reward is that once your aquarium is up and running, you'll be able to sit back without worrying about maintenance and enjoy the fascinating underwater world you've created, whenever you please.

It's worthwhile to have a good filtration system, as maintaining a stable biological system is critical to your fishes' good health
Set up your aquarium, wait for one to two weeks to cycle before you purchase any fish. It is important for the cycling process to be established before you add any fish to the aquarium.

Clean your aquarium every three weeks with partial change of water IF your tank is over crowded. Remove 25% of the water and top up with same amount. New developments in the aquarium industry have made it even easier than before to maintain an aquarium.

Note: Water level will stay with or without power supply.
Only partial change of water is required.
