For a 30-liter BiOrb fish tank, you should fill it with approximately 30 liters of water, accounting for any decorations, substrate, and equipment that may displace some volume. It's important to leave some space at the top to prevent overflow and ensure proper aeration. Additionally, always treat the water with a dechlorinator before introducing fish.
The BiOrb retailers recommend at least 24 hours, and I would say definitley no less time than this. I was advised at 3 days, and I have now had 3 fish in my BiOrb for 2 weeks with no water or filtration problems.
BiOrb aquariums can be purchased through Amazon and other online retailers. I am sure your local petshop would sell at least one variety of BiOrb aquariums.
The biorb fish tank is made of glass or plexiglass like other fish tanks, except it has a ceramic filter inside so that when the fish uses the bathroom, it sucks it out quickly.
Petco has them, so I'm sure Petsmart does as well. Amazon also has them. There is also an online store called Everything Biorb that has them, as well as a store Biorb Fish Tank, which is also online only.
I am not sure of the absolute mathematical sizing, but I can recommend my 4 gallon tank which I think is one of the more convenient sized ones. I have a 30cm by 30cm round fish tank made by BiOrb - it is a baby biorb.
It depends on how much water and how pressure is on the tank.

It is recommended to change about 25-50 of the water in a fish tank every 1-2 weeks to maintain good water quality for the fish.
With or without a heater they are not suitable for keeping any kind of fish in. The 3 basic rules of fish keeping are :- 1 inch of fish needs a minimum of 1 gallon of water. :- every fish tank need a permanently running cycled filter. :- every fish tank needs to have at least 50% of its water replaced every week. If you follow the above three rulles you and your fish will stand a chance of success. If you fail in keeping them I can guarantee you will be constantly having problems and be buying replacement fish.
Your fish will be much happier if you change at least 50% of the tank water every week.
It depends on the type/brand of conditioner, and how much water is the Betta tank can hold.
To do a water change in a fish tank, first, prepare new water that is the same temperature and treated with a water conditioner. Use a siphon to remove about 25-50 of the tank water, being careful not to disturb the gravel or decorations too much. Pour in the new water slowly to avoid stressing the fish. Repeat this process regularly to maintain a healthy environment for your fish.
