• Convert inches to gallons

Why do goldfish need more gallons per fish than normal aquarium fish?

• Goldfish need 8-10 gallons per fish.
• They tend to be dirty and their bodies are fatter.
• Goldfish feed at the bottom of the tank.

Using a good water testing kit to measure water parameters such as ammonia, nitrites, and nitrates leads to having?

If your water still has nitrates levels over 40-50 ppm after proper feeding and proper water changes, then ________________________________.

• you have an overstocked aquarium

• you have an under stocked aquarium

What is the single most important factor for having a successful aquarium?

• filtration system

• proper amount of surface area

• Partial water changes

• only have fish that measure under 3 inches

What type of filtration removes ammonia and nitrites as part of the natural process called the nitrogen cycle?

• mechanical filtration
• chemical filtration
• biological filtration

If you are going to do a 20% water change in a 50 gallon aquarium, how much water are you going to replace?

• 10 gallons
• 5 gallons
• 7 gallons

Which one of the following is not a water parameter that we would test or measure.

• Temperature
• Salinity
• Nutrients
• Ammonia

What is the name of the bacteria that converts nitrites to nitrates? Look at the diagram

• Nitrosomonas

• Nitrobacter

• Ammonia

• Nitroconverteria
