Which design or size should i choose.

The design is for you to choose. After you got the design, go for the biggest tank you can place at the location you wanted. More water means better water quality and more space for your fish.

Location for your Biorb Tank

  1. Avoid location that has direct sunlight as that will promote algae
  2. Provide a strong base to support the tank


Technically, the Biorb Tank comes with everything you needed to set up a tank. Other than decorations, you do not need to get anything else but we will cover that later in this article.

Video below shows you how to setup your biorb tank.

Now, to the maintenance part.


We recommend getting the below items for healthier fish and cleaner aquarium.

Water conditioner (Chlorine removal)

  • You need to add this during every water change to remove chlorine in the tap water as chlorine is harmful and will kill all the living things in the tank.

JBL Biotopol 

Beneficial Bacteria

  • We highly recommend adding beneficial bacteria as it helps to keep the water clean by breaking down waste naturally. This prevents nuisance algae or toxic from growing, keeping the fish safe and healthy.

 Aquaforest Bio S.  (Add 1 drop every time)

Water changing device

  • This will help you to change water easily


Daily - Add Beneficial Bacteria everyday for 1st month (3 times a week after 1st month)

Once a week  -  30% water change

Once a month - Change the filter. There are 2 ways of doing it.
1. Easiest way - Change the whole filter cartridge

2. The cheaper way - Change the carbon in the filter cartridge and wash the filter sponge with aquarium water

(This product have volume of about 10 - 20 times changes)

Half a year (optional) - take the ceramic media out and wash it with aquarium water


Only feed the amount of food your fish can finish in 1 minute. Do not put all the food at one go. Split into 3 portion and feed only when 1 portions is finished. This will prevent leftover food sinking into the bottom. Remove any leftover food.


Light up aquarium for not more than 8 hours per day and do not place aquarium near sunlight as that will promote algae growth.
Do not switch on white colour if you would like to switch on for longer duration.
