Features

  • 【Hygger Aquarium Kit Includes】one 7W 110GPH internal power filter pump, one colored led aquarium light, one 8 gallon glass tank with a decorative 3D rockery mountain background. The 3D background makes the whole aquarium looks cool like a dream word underwater, is a great rest, play spot, shelters for little fish. Also you can plant some green grass on the rockery mountain.
  • 【Mutil-modes LED Light】The aquarium led light is DC12V/18W, with extendable brackets, length can be adjusted from 0 to 19 inch. It has a external digital controller, you can use it to set the lighting time to 3, 6 or 12 hours, to adjust the light brightness from 100% to 10%, 5 levels of brightness in total, to shift the light modes: White LEDS, Blue+white+red LEDS, Red+ blue LEDS.
  • 【Durable Power Filter】The aquarium power filter is 7W 110GPH, for 2-8 gallon tank use. It's a super quiet and durable filter, and can be use for low water, the upper part is the 2 stage filtration system, the bottom part is water pumping systerm to pump the water upward. Please NOTE this filter may be too strong for small fish that is not long than 2 inch, may suck small fish, if you keep small in the tank, please don't run the filter or don't run it all the time
  • 【New View Curved Tank】Tank size: 19" L x 11.8" W x 9.6" H. This glass fish tank has a unique convex arc curve shape, can widen your view on the aquarium, and can hold more capacity of water. The total tank volume is 8 gallon, it can hold 6 gallon of water, because the tank has a undetachable 3D background decor. When it holds full water, the whole tank weighs about 68 pounds.
  • 【Multi-protection Packing】We used 3 layers of packing to pack the aquarium kit and with light lifting label, the innermost layers is a super sturdy poly foam with excellent cushion. We have done the shipping test by sending 3 of the packs to 3 different distance places and find the glass tanks are still in good condition when received. So don't worry the tank will not be broken during the shipping, if you find tank broken when open the package, please take a photo and send it to the seller.
