How to Start a Freshwater Aquarium the Right Way

A Healthy Aquarium

Fish keeping can be a rewarding pet hobby be they tropical or goldfish. Watching healthy fish is one of the best stress relievers around. But there is a right way to start that will save money and fish lives in the long run and the key is patience. This method comes from a 20 year experience keeping fish and breeding goldfish and koi in aquarium and pond environments.

Difficulty: Easy

Instructions

Things You'll Need:

• Aquarium - how many gallons is up to you
• Aquarium Stand
• Light
• Under Gravel Filter
• Power Filter
• Heater only for tropical fish
• Gravel
• Natural rocks
• Air Stone
• Plastic or real plants
• Dechlorinator
• Starter bacteria or a cup of water from an established aquarium

1. 1
   PLACEMENT AND PUTTING IT TOGETHER - Many aquariums come in a kit of some kind that includes light, filter and heater. Stands are often sold separate. Set the aquarium up in a location where it will not be hit by direct sunlight to avoid excess algae growth. Some aquariums will come with a light and filtration system all in one in a top. It all depends on what company it comes from. The light should ideally be full spectrum like daylight especially if you want to grow live plants. Live plants are not recommended for gold fish as these fish are vegetarian and will destroy any planting. Both a power and under gravel filter should be used to provide both mechanical and biological filtration especially with gold fish as they produce more waste. Power filters are rated according to how many gallons the tank is to insure you purchase the right one for the job. Install the heater only if you will house tropical fish. The air stone is needed in both cold water and tropical environments to keep the water well oxygenated. They come in many sizes and styles and can be hidden among the aquarium decor.
2. 2
   GRAVEL & DECOR - Once all the under gravel filter parts are put in place put in gravel after it has been rinsed of all dust. This should be two inches deep in front and built up in a hill three inches or so at the back. Place the plants in next making sure bases are well buried if plastic and roots well covered if live. Natural rocks may be added for an interesting underwater landscape after they are washed in salt and water or plastic rocks may be used. NEVER USE SOAP on anything in the aquarium or you will kill the fish. It is best not to add any of those air powered animated curios as they contain too many sharp edges that can injure fish. An underwater landscape that is natural is better. Also avoid sea shells as the calcium and lime content can cause a water chemistry imbalance.
3. 3
   WATER & FILTRATION - Water can be added at this point, but be gentle so plants and other decor are not disturbed. A good way is to pour the water slowly over the largest rock to disburse the force. Fill the aquarium to within an inch of the top. Start up the filters and put in the dechlorinator. Let the filter run over night to rid the water of cloudiness caused by gravel dust and then add a starter culture of good bacteria or a cup of water from an aged healthy aquarium that will set up a colony in the filters.
4. 4
   FISH - This is often the hard part for those starting in the hobby. Let the aquarium age one to two weeks before putting in any fish. The reason being the live plants need to get acclimated and the good bacteria need time to grow. This is crucial for a healthy aquarium. When fish are added a good formula to avoid over crowding is for tropicals two inches of fish body length per gallon and for goldfish one inch of fish body length per gallon. For a healthy aquarium DO NOT put goldfish in with tropicals. They have different temperature needs. Gold fish prefer and are healthiest in water around 65 degrees. Do not add all the fish at once as it will shock the filtration system and a cloudy water will indicate a bacterial problem. It is best to add one or no more than two fish at a time.
5. 5
   AQUARIUM HEALTH - To keep everybody healthy test water for acidity once a week and adjust the PH according to what the species of fish prefers. Kits are available for this. Water changes are also done according to species. A good recommendation for tropicals is a 1/3 change of water once a month with a check, rinsing or change of filter pads and charcoal that should be done at this time. For goldfish a 1/3 change of water should be done twice a month with a check, rinsing or change of filter pads and charcoal. Goldfish should NEVER be kept in a bowl as it gets toxic very quickly with waste with no filtration. Feed according to species and DO NOT overfeed. Remember fish are always hungry mainly because that part of their brain does not shut off. Your local pet shop should carry a good variety of dry and live food.

Tips & Warnings

• Remember water is heavy at about 7 pounds per gallon so aquariums are best located by a load bearing wall.
• DO NOT locate the aquarium by a window as sunlight will cause a massive growth of algae.
• DO NOT put a heater in a goldfish aquarium as they are cold water fish.
• DO NOT house tropical and goldfish in the same aquarium as they have different temperature needs.
• DO NOT house fat bodied goldfish (fan tails) with slim goldfish (comets and commons) as the slim ones will chase the fat ones thinking they are ready to breed (fat with unfertilized eggs) The stress will kill the fat bodied ones.
• DO NOT put sharp edged rocks or other ornaments in the aquarium as it can cause damage to any fish that bumps it. Any injury will become infected.
• DO NOT put sea shells in any fresh water aquarium. It causes a problem in water chemistry.
• DO NOT overfeed. This is a main cause of fish death mainly because uneaten food fouls the water creating colonies of bad bacteria.
