1) Gravel
- Gravel helps for Biological Filtration.
- Help for the Growth of live Plants.
- Different Sizes are available in the Market
- Gravels which are made by chemicals or Chemical Coated or Painted Should be Avoided
How Much Gravel is needed for Aquarium?
- 2 To 3 inches of Gravel is Must and Should
- A Bed should be created in Aquarium, and Natural fresh water stones are higly preferred as they help us in Maintaining the PH level of water.
How to Clean Gravel?
Never Wash Gravel in Soap water or any other chemical which may harm the Fishes.
Never Clean all the gravel in an Aquarium at A time, it will destroy the Nitrogen Cycle
Half at a Time Cleaning is Highly preferred...
These days we can find good number of Gravel Cleaners.... by using them we need not to remove the gravel from Aquarium too..
2) Air Pump
- First and Important thing i would like to say here is Air Pump Doesn't provide Oxygen Directly.. In-fact it helps to increase oxygen levels in Aquarium by breaking the Water Surface.
So is it Compulsory to Have Air Pump in the Aquarium?
It is the most Discussed Question in Aquarium forums i have to say..
I suggest to Buy one irrespective of the size of Aquarium...
Fish wont feel uncomfortable with the bubbles...
There are only Advantages of having the air pump..
Few are
Oxygen levels are improved..
Bad Gases are exhausted in the form of air bubbles..
Helps to Create waves.. by which fishes can have a natural feeling...
One suggestion here is...
Go for Stone Rather than Decorative Air Bubblers....
Reason here is simple.. Air Stone breaks the surface more than any decorative bubblers...
