This is a low profile background hood made from black plastic. The Aqueon LED background hood comes in 4 different sizes for 20-gallon tanks: 20”, 24”, 30”, or 36” inches. Within this size range, most 20-gallon rectangular tanks are compatible.

When you order it, you will receive the standard daytime bulb. A separate night time bulb is also available. There is space for installation of a second bulb in the built-in fixture.

On the back, sections are cut out for your tank accessories. Each section is large and spacious, so you have options for filters, heaters, etc.

For feeding and other water adjustments, lift the lid at the front of the hood. The lid rests open, making it easy for you. Closing the lid seals off the tank again for reduced evaporation and heat loss.

A light switch sits on the back right of the hood. The cord also comes out from this part of the hood.

Sitting lower on the top, this MarineLand LED light hood has a beautiful low-profile appearance. It rests cleanly on the edges of the tank, creating a better seal for preventing evaporation.

Rather than a clunky light bar, LEDs are set in the middle of the hood. There’s a visible bump. But, it’s round and smooth for a better overall aesthetic.

The LEDs in this hood are built in. They hold on securely to the top of the hood when you open it. If the lights go out or if you want to replace them, remove the light bar and put in a new one.

This comes in 3 different sizes for 20-gallon tanks: 20 x 10, 24 x 12, and 30 x 12 inches. These dimensions are compatible with a range of 20-gallon aquariums, so you’re not limited in your options.

There is space on the back for filters and other accessories in a large cutout. Hinges at the back allow the entire hood to be opened for water maintenance or feeding. There is also a smaller opening for feeding.
