FAQs About Aquariums, Kits & Stands
Here’s how to set up a freshwater aquarium or a saltwater aquarium.
This depends on whether you’re adding fish to a new or existing tank. If the tank is new, you should only add your first fish to properly cycle your fish tank. The aquarium must be completely cycled before new fish can be added safely, which could take a number of weeks. If adding fish to an existing tank, they must properly acclimate before being introduced to their new habitat.
With fishless cycling you will need to start the cycle before your fish arrive so that the tank is ready once they are received. Since there are no fish you will need to add ammonia to replicate the waste your fish will produce. Fish-in cycling should start with only a few fish. They should be fed lightly at the start then gradually increase the feeding over the next 4 to 6 weeks.
The general rule for how many fish can be in one tank is one inch of fish for every gallon of water. For example, a five gallon tank can accommodate five inches of fish, a ten gallon tank accommodates ten inches, and so on.
Keep your pet's home tidy with monthly cleanings. Even the cleanest tanks have some algae and debris — they accumulate on the sides of the tank, in tubing and filters, and on accessories. No chemical cleaners are needed. Dismantle filters and lift tubes to remove clogged debris. Stiff brushes make it easy to clean your tank. Magnetic cleaning blades or scrub brushes with long handles help you remove algae from the tank's sides.
