Frequently Asked Questions

What do I need to set up a freshwater aquarium?

Typically, freshwater aquariums are easier to maintain, less expensive and present fewer risks than saltwater aquariums. You can start a good freshwater fish tank with around $300 - $500 (not including fishies and food). To set up your freshwater aquarium, you’ll of course need to start with a tank. After you get your tank, you’ll also need a pump, a filter, ornaments, and an aquarium heater. A light source is also required if your tank will not be receiving direct sunlight. Just like us humans, the average aquarium needs about 10 hours of light per day to function normally. Tropical fish and plants need 12 hours of light a day, and cold-water fish and plants require eight hours a day.

What should the pH and CO2 levels of a freshwater fish tank be?

Most aquariums require a pH of between 6.5-7.8, and a CO2 level between 15-30 mg/litre with 20-25 mg/litre being ideal. Just remember, you don’t want your fish tank to look basic, but you do want your pH levels to be. Water treatments are available to lower and maintain pH in your aquarium.

What temperature should my freshwater fish tank be?

It can be tricky to get your aquarium to the perfect temperature. Generally speaking, you’re going to want to keep your fish tank between 22°-26°C. Depending on what kind of fish you have, you may need it a few degrees warmer or cooler. It would be wise to purchase an aquarium heater for your fish tank, ideally with a thermostat. If your heater doesn’t have a thermostat, you can purchase a thermometer to go along with it.

How to clean a freshwater fish tank

To clean your tank, use an algae scraper or pad. Make sure to buy a magnetic scraper designed specifically for fish tanks. For more information, refer to our blog on properly cleaning your tank.
