Tetra is a name you can trust in the aquatics industry. With decades of proven performance and high quality products it’s no wonder Tetra is the go to brand for aquatics beginners and veterans alike. Tetra makes all the difference with the Tetra Internal Filtration System. It utilizes a 2 part filtration system. The first is mechanical filtration where the filter pulls water out of the aquarium and pushes it through the filter cartridge where the dense, dual sided mesh catches debris and waste. The second step uses chemical filtration where Ultra-Activated Carbons remove odor and debris. Not only does the Starter Kit come with the Tetra Internal Filtration System but it also has the power of ColorFusion LEDs that illuminate bubbles with a rainbow of color from red, yellow, blue, green and everything in between. Feeding and maintaining your fish is easy with this aquarium because it also includes a feeding tube.
