If you are looking to maintain biorb fish tanks, you will have many options to consider. The first one should be the filtration system you use. Good filtering will help an aquarium maintain its own upkeep. Instead of letting dirt, settlement and gunk build up, the tank’s filter actively removes it. This not only cleans the water, but it also provides the fish with a better, more comfortable living environment.
There are plenty of diseases that can injure or kill fish. Having them in a fish tank does not mean they will be safe. Sure, there is less opportunity for threats to establish themselves. However, a fish tank is a closed ecosystem. Anytime you add water from another source, you are essentially changing that eco system. This is especially true after you have bought new fish and have brought them home, in a bag of water the seller provided.
This is why filtering is so important. It helps reduce the threats from freshly added water, but there is another thing to consider. Fish are living, breathing and eating creatures. They must intake food to sustain themselves, and whatever goes in must also come out. To put it bluntly: fish produce poop. That waste is in the water until the tank is cleaned or the water is actively filtered. The longer a tank goes without a filter, the more of the fish’s waste products build up in the water, the dirtier and more disgusting that water becomes.
Biorb fish tanks are of high quality, not only in the how it works, but also in it’s filtration system. This will provide a lot less to worry about. Still, just because a biorb tank has a filter doesn’t mean the water can sit forever. Periodically, a tank will still need to be cleaned out. However, the filtration system will keep this at a minimum.
