The attraction of having your own aquarium speaks for itself. It means that you have access to this as your own personal resource to aid relaxation in your own surroundings 24-7, all year round. It can provide you with a very good and interesting hobby which is achievable within most people's budgets and with limited time and effort required.
One aspect that people tend to overlook is the necessity of fish tank care so that the duty of the proper cleaning is carried out to ensure a proper hygiene level which is an essential for the health and wellbeing of your pet fish. If you don't take the trouble to do this necessary cleaning chore, you will be putting in danger and finish up having a cloudy fish tank. There is no other factor that has a more important effect and plays an essential part in ensuring that your fish along with other aquatic animals and plants maintain a high level of health and happiness which in turn gives us the benefit of watching them for many years to come.
Over a period, black algae could form over the surface in the tank and together with waisted food that builds up in the sand at the foot of the aquarium will result in a maintenance problem. The answer lies in tackling the potential problem before it arises by employing the help of algae-eaters and bottom-feeders such as catfish for example. These help in your fight against debris building up on the bottom and algae being allowed to get out of control on the sides of the tank. There are particular water creatures which fall into the category called "scavengers" and they come in all shapes and sizes, from tiny crabs to medium sized fish. Each one of these creature serve a specific purpose and you need to make the correct selection. The most of these will gorge themselves on the black algae which in turn helps to limit it. You need to be aware how the various species get along with each other, as some especially the larger species have the tendency to chase, harass and even eat the smaller ones.
All this said, you will have to monitor the chemistry of the water and replace perhaps 10% at any one time. Fish abhor huge changes hence the recommendation to gradually change it instead of all in one go. This important time spent on fish tank care will benefit you in the long run and prevent problems such as black algae and having a cloudy fish tank causing your fish to become unwell.
