Freshwater Aquariums
Environmental
A well-made aquarium is essential for supporting the weight of all the water. Most aquariums consist of glass or acrylic.
Range in sizes from 7.6 L (2 US Gal) to 760 L (200 US Gal).
larger the aquarium, the easier it is to maintain and the the healthier the environment is for your fish.
A tank between 38 L (10 US Gal) and 125.4 L (33 US Gal) is ideal for someone starting their first aquarium.
Aquarium Stand – Water is heavy! It weighs more than 3.63 kg (8 lbs) per 3.8 L (1 US Gal). Many bookshelves or side tables will not support that much weight. As well, you will require a place to put your filter and other equipment.
Aquarium Canopy – A well fitting cover protects the fish from outside contaminants and helps to reduce temperature fluctuation and evaporation.
Gravel – Simulate your fishes’ natural environment. It will retain solid debris and provide substrate for live plants to grow in.
— Average amount of gravel required is 0.6 to 0.9 kg per 3.7 L of water (1 ½ to 2 lbs per gallon), creating approximately 5 cm (2 in.) on the bottom of the aquarium.
Heater and Thermometer – A heater is necessary to maintain a constant temperature of 24°–25°C (76°–78°F), which is comfortable for most freshwater fish.
— Fish are sensitive to temperature fluctuations, so investing in a quality heater that is easy to set and adjust is good sense. You need a thermometer to read the temperature of the water.

Light bulbs
Light Fixture and Bulb(s) – Light fixtures are available in LED, fluorescent or incandescent. LED lighting is an energy efficient light source that produces a bright light, which provides amazing colour and shimmering effects for fish.
LEDs are used in aquarium light fixtures as supplementary or independent light sources.
Fluorescent lights create a bright, natural appearance to any aquarium.
Both LED and fluorescent bulbs operate at a cooler temperature, which is less likely to affect the temperature of an aquarium.
Incandescent lights do not illuminate your tank as well, and they create heat. Although they are less expensive to purchase initially, you must replace incandescent bulbs more often.
Freshwater
NUTRITIONAL
A Variety of Food – All fish are constantly searching for food. In their natural habitat they will find many varieties of tasty morsels.
— Flake foods and pellet foods provide a staple diet and you should offer these daily.
Adding different foods, such as freeze-dried tubifex worms, frozen blood worms or algae discs will help to keep your fish healthy and colourful! You should feed your fish two to three times a day.
Ensure that your fish eat all the food, since uneaten food may pollute the aquarium.
Freshwater
BEHAVIOURAL
These are necessary to give your fish a place to retreat and swim around.
Just as you would be uncomfortable in a room without furniture, your fish need their decorations for security.
Live, silk or plastic plants, driftwood, artificial decorations and aquarium safe rocks enhance the beauty of your freshwater aquarium.
The general rule is to create one hiding spot per fish.

MAINTENANCE
Filter Systems – A filter serves to remove toxic waste in the water created by your fish and decaying fish foods.
Power Filters – We offer these filters in many styles that can be placed inside (internal), hang-on (external) or underneath (canister) the aquarium. An internal motor powers these for quiet operation. They have convenient cartridges to clean or replace. Power filters use three styles of filtration: mechanical, chemical and biological.
Gravel Cleaning Siphon – A gravel cleaner is like a vacuum. It sucks up dirt, debris and toxins that you may not see, which are present in the water and gravel. Gravel cleaning your aquarium by removing 20 – 25% of the water every three to four weeks will reduce the accumulation of toxic waste. Partial water changes are the single most important procedure you will perform on your aquarium.
Water Conditioner – This removes the chlorine and neutralizes heavy metals in the water. Many also have a natural additive that replaces “slime” lost by stressed out fish.
Bacteria Supplement – the use of a bottled bacteria additive will help kick start your aquarium by eating up the harmful toxins produced by your fish and assist in developing a biological cycle.
Algae Scraper – This removes unwanted algae growth that may appear on your ornaments and tank glass.

Setting up the tank
Since you are setting up a new environment for your fish, you may need to wait a couple of days to allow the aquarium to acclimatize before adding fish. Start populating your tank with just a few hardy fish.
Your aquarium will take up to two months to create a healthy biological environment. Be patient, add fish and live plants slowly.
Freshwater
Introducing New Fish into Your Aquarium
Travelling from one aquarium to another can be very stressful for fish. Extreme temperature changes (hot or cold) can adversely affect your fish’s health
During this period fish may be unable to produce or repair their slime coat. A fish’s slime coat is their natural protection against injury to skin, scales and parasitic infestations such as Ich (which can be present in established aquariums).
Wrapping up your fish bag in paper or keep them inside your warm jacket. Go directly home to lessen the transport time.
When you arrive at home, float the sealed bag of fish in your aquarium for 10 – 15 minutes to allow the water temperature in the fish bag to adjust to the aquarium’s temperature.
While you are waiting, add new decorations or rearrange the decorations in your aquarium to create new hiding places for all your fish.
Use an aquarium fish net to transfer only the fish from the fish bag into your aquarium. Discard the water and the bag. Then add a bacterial supplement to boost the biological filtration in your aquarium, which will benefit all your fish.
To help reduce health problems, we recommend adding a full dose of water conditioner as a slime coat additive, and aquarium salt (if permitted) as an electrolyte booster.
Monitor your new arrivals, along with your other fish, for the first 48 hours. Look for signs of stress, such as loss of colour, clamped or frayed fins, unusual grey patches or white spots and a lack of appetite.

Aquarium Salt - A Healthy Prevantative
Adding Aquarium Salt Can:
It does not contain iodine like ordinary table salt. It does not contain trace minerals like that of sea salt.
Aid in the treatment or control many parasitic populations (including Ich) when added to the aquarium if used properly.
Enhance your fish’s ability to produce a protective slime coat. This is especially helpful if your fish are recovering from a bacterial infection or an injury, such as a torn fin.
Prevent intake of lethal nitrites during the nitrogen cycle when starting a new tank.
Lessen stress by aiding gill function. Fish kidneys are designed to excrete the water absorbed through the fish’s skin and gills. This is a big job and a constant one necessary for your fish’s survival.
By adding aquarium salt to the water, the fish’s kidneys do less work, because the amount of water absorbed into the blood by way of gills is reduced.
Aquarium Salt
When and How To Add Salt
Products give usage instructions on their aquarium salt packages.
Some hobbyists use aquarium salt only as a general tonic or preventative. Others use it in higher concentrations to treat for existing parasites. It can even be used to hatch brine shrimp eggs.
As An Illness Preventative:
It is not necessary to add aquarium salt all the time, although some fish like
Goldfish and Livebearers benefit from maintaining a constant level of one tablespoon for 5 gallons of aquarium water.
Aquarium salt should always be pre-dissolved in a container of water before being added to the aquarium.
The salt concentration in an aquarium increases with evaporation. Do not add aquarium salt when replacing water due to evaporation.
When you are performing a water exchange on your aquarium, you can add more aquarium salt. Only add the amount of salt based on the amount of water you removed while syphoning with your Gravel Cleaner.
Preventative Dosage:
One teaspoon of Aquarium Salt to 1 ½ gallons of water.
Two teaspoons of Aquarium Salt to 3 gallons of water.
One Tablespoon of Aquarium Salt to 5 gallons of water.
Aquarium Salt
When Aquarium Salt is Used as a Disease Treatment:
Salt is most beneficial when used in combination with other medications when treating ill fish.
The concentration of aquarium salt used can slowly be increased for aiding ill fish.
As a general rule, start with one tablespoon of salt for 5 gallons of aquarium water. This is a safe dosage for all fish.
Observe the aquarium for 24 hours. The addition of aquarium salt increases the fishes’ activity level, decreases laboured gill movement and the fish should show signs of improved coloration.
If there is no improvement, the salt dosage can be repeated for up to four days.
On the fifth day, perform a 25% water exchange.
Repeat the water exchange once a week for four weeks without adding more aquarium salt to slowly reduce the salt concentration.
Aquarium Salt
Aquarium Plants, Bottom-Feeders & Delicate Species
Although the benefits of aquarium salt are many, there are a few drawbacks that freshwater hobbyists need to consider before adding it to their tanks.
Live plants cannot survive in treatment concentrations of aquarium salt. Some plant species should not be kept in aquariums containing aquarium salt.
Fish spawning, as well, can be affected by addition of salt because it can dehydrate eggs and kill sperm emitted by male species.
Some fish species, especially bottom feeders like Chinese algae eaters and Corydoras catfish, are sensitive to aquarium salt and may become distressed if concentrations are too high.
These fish may adjust to a low concentration of aquarium salt in their water if the desired concentration of aquarium salt is added over several days.
Therefore, hobbyists should avoid dumping all the aquarium salt into the tank at one time if delicate species are in the tank.

Setting Up Your New Aquarium
1. Before you start setting anything up, take an inventory of your supplies. Rinse all your equipment (including the aquarium) in clear tap water to remove any contaminants.
2. Place the aquarium on an appropriate aquarium stand, away from direct sunlight, as well as heating and cooling vents. Be sure the tank is sitting level. Fill the aquarium with 4 cm (1 ½ in) of water. Rinse the substrate (gravel/sand) thoroughly. The gravel should be sloped higher in the back to allow for better decoration anchorage.
3. Fill the tank half full of water. Pouring the water into a temporary container (2 cups), placed inside the aquarium, will prevent the gravel from being disturbed and reduce a cloudy appearance. Next, add plants, rocks and driftwood to create an environment your fish will thrive in. The decorations should be arranged in a horseshoe-shaped diorama to provide adequate hiding places for your “wet pets.” Oddly enough, the more decorations you have, the more visible your fish will become. The centre of the aquarium should be mainly open to allow for a free swimming area.
4. Finish filling the tank with water and then remove the temporary container. Place the aquarium heater in the tank but do not turn it on at this time. Allow the heater glass to acclimate to the water temperature in the aquarium for one hour before plugging it in. You can camouflage the heater behind the decorations. Put the thermometer in a place opposite of the heater.
5. Equip the aquarium with a filter system. If using an internal filter, place it in the tank toward the back and hide the filter using plants or driftwood. If you are using an external filter, place it at the back of the tank or underneath. Hide the intake tube, which draws water from the tank to the filter, with decorations, but still allow for circulation. Add water conditioner to the aquarium, and turn on the filtration system. Be sure to prime any pumps with water, prior to starting.
6. Test the pH and water hardness of your aquarium using an aquarium test kit. Make any necessary adjustments to the water using the proper water condition supplements to recreate an environment specific for your fish. Creating a similar pH and hardness to your fish’s natural habitat will help to alleviate stress and produce brighter colours in your fish.
7. Now place the aquarium canopy in position and make any adjustments (cut outs in the back) to accommodate the heater, filter and cords. Plug the canopy light into an automatic light timer and set the timer for 10 to 12 hours a day.
8. Plug in the aquarium heater and make any final adjustments to the heater in order to stabilize a temperature between 24°–25°C (76°–78°F) depending on the fish you have chosen. Make adjustments every half hour until the desired temperature is achieved.
9. Wait one to two days before adding fish, to ensure the correct water temperature and everything is running properly. Adding fish too soon after the initial set up can be unsafe for them. Constantly fluctuating temperatures or too much suspended debris dangerously increases their stress level.
Setting Up Your New Aquarium
Testing the water
All new aquarium set ups need to develop beneficial bacteria to create a biological cycle in the aquarium.
This filter conditioning process is referred to as “New Tank Syndrome.”
This takes approximately five to seven weeks to develop, depending on the specifics of each aquarium.
We recommend using a bacteria supplement to assist in developing a biological cycle in the aquarium.
Over the next several weeks, we recommend weekly water quality testing.
When the water tests of ammonia and nitrite reach zero, more fish species can be added.
For your convenience, we recommend the appropriate water test kits which will allow you to accurately test your aquarium water at home.
