The size of the water tank was determined based on the volume required to maintain adequate thermal mass for each dome size. Approximate volumes for the water tank are:
• 15′ Growing Dome ~ 600 gallons
• 18′ Growing Dome ~ 700 gallons
• 22′ Growing Dome ~ 1,000 gallons
• 26′ Growing Dome ~ 1,200 gallons
• 33′ Growing Dome ~ 2,300 gallons
• 42′ Growing Dome ~ 3,200 gallons
We also highly recommend you have a variety of aquatic plants in your water tank to prevent algae and provide nutrients for your fish.
