If you are finding an aquarium to get started your first journey of fish keeping and don’t care about what size it is, a 20 gallon aquarium kit will be the best choice for you. However, if you only love large tanks, 40-50 gallon ones are great sizes to go with and the SeaClear 50 gallon acrylic fish tank is a great option for you. It is available in three backdrop colors (black, clear, and cobalt blue) for you to choose.

The best thing that makes this acrylic aquarium chosen from other options is its very seamless and clear acrylic view from the corners to the sides. The acrylic material used in the manufacturing of the SeaClear model permits light to shine through better. There is absolutely zero visible tint or sealant on the aquarium, which boosts the lifelike aspect of the flora and fauna inside.

The tank can be used for both freshwater or saltwater applications because all its manufacturing materials are entirely safe for these types of aquariums. The top of the tank features some pre-cut holes for placing a filter and heater. The only bad thing about this product is its hood, which uses old-technology fluorescent light. Luckily, you can absolutely replace the fluorescent hood with a 36-inch LED light fixture. The tank will look so great with this small modification.
