Total 3-Stage Filtration Efficiency
Three types of filtration are necessary for a healthy, successful aquarium.
Mechanical Filtration traps solid debris like fish waste and uneaten food. The polyfiber filter pad traps dirt and debris.
Chemical Filtration uses activated carbon to attract and hold dissolved pollutants, which can cause discoloration and odor. The filter cartridge supplies both mechanical and chemical filtration. Each cartridge is packed with Diamond™ Premium Activated Carbon.
Biological Filtration depends on a culture bacteria to get rid of ammonia and nitrite that build up in the aquarium water. Harmful ammonia and nitrite are changed into harmless nitrate by the bacteria, which is removed with a partial water change. The patented Eclipse BIO-Wheel rotates, providing bacteria with the oxygen they need to grow, flourish and remove ammonia. The BIO-Wheel never clogs, never needs replacing, and requires virtually no maintenance.
Set-up:
Because your Eclipse aquarium is made of acrylic, it is susceptible to scratching. Take care when handling the aquarium or when adding decorations, rocks or gravel. Never use glass cleaners or abrasives of any kind - always use an acrylic cleaner or damp terrycloth towel.
The Eclipse System Twelve Aquarium is one of the simplest aquariums to own. Whether you are a beginner or an accomplished aquarium owner, you will appreciate the convenience of this self-contained aquarium.
In addition to your Eclipse System Twelve Aquarium Kit, you will need to buy these supplies to get your aquarium up and running:
Gravel: Coated or pre-washed is ideal.
Decorations: Use only plants and ornaments designed for aquariums.
Additional Water Conditioner: Declorinates tap water for future water changes.
Net: For transferring fish.
Gravel Washer: For water changes and cleaning.
Heater & Thermometer: If housing tropical fish.
Choosing a location for your aquarium
Always place your aquarium in a location designed to support its total weight. The Eclipse System Twelve will weigh approximately 120 pounds when complete. Always place your aquarium on a flat, level surface with an electrical outlet near. Never place your aquarium near a heat source or air conditioner. Never place your aquarium in direct sunlight. Full or even partial sunlight can cause excessive algae growth.
Preparing Your Aquarium
Prior to setup: Use a clean, damp cloth to clean your tank inside and out prior to setup. Never use soap, detergents or cleaning agents.
Adding gravel: Add 1-1/2 to 2 pounds of gravel for every gallon of aquarium water. Be sure to rinse the gravel thoroughly (water should drain clear) before adding.
Filling your aquarium: Pouring a stream of water directly into your tank will disturb the gravel bed. We recommend before adding water, you place a clean dish on the top of the gravel and gradually pour the water over the dish. The stream is gently deflected without displacing gravel. Always fill your aquarium with room temperature water. Cool water produces condensation, which gives the appearance of leakage. If condensation does occur, simply wipe surface with a clean, dry cloth until temperature stabilizes. Always treat water with a dechlorinator before adding it to your aquarium; if your tap water contains chlorine, it will be toxic to your fish.
Adding decorations: Once your aquarium is half full, you can add aquatic plants (live or artificial) and/or decorative rocks and ornaments. Before adding any of these items, be sure to rinse them thoroughly. When placing plants, it is a good idea to locate larger ones to the rear of the tank, smaller ones toward the front. This ensures an open swimming area for your fish. When all ornaments and plants are in place, continue filling the aquarium to within an inch of the top rim.
Adding heater and thermometer: A 50-watt heater and a small, stickon thermometer is recommended when housing tropical fish. Plug in heater ONLY after it is submersed in water to its required level.
Before adding fish: When creating a new aquarium, allow your system to operate for at least 24 hours before adding your fish. If in doubt about what type of fish to select, talk to one of our customer service people and they can help you select the best fish for your aquarium.
Adding your fish: Add only a couple of small fish at first, then wait 4-6 weeks before adding more. Choose fish that appear to be healthy and active. Make sure the water in your aquarium is the same temperature that your fish are currently in. To equalize the two temperatures, float the transport container in the tank for about 15 minutes. Then, at 5-minute intervals, open the bag and add a small amount of aquarium water. Finally, net the fish and transport into the aquarium. Do not add the bag water to the aquarium. Let the fish swim from the net into the tank, the less traumatic the transport, the better for the fish. A 12-gallon aquarium can eventually house up to 12" (adult size) of fish, although less fish can mean less water changes.
