An Absolute Must For All Bare-Bottom Aquariums

Overall Dimensions - 23 3/4" x 23 3/4" x 1/8"

Bare Bottom tanks have been around for a long time, and come with a lot of benefits, but they leave the bottom of your tank unprotected, and depending on the aquarium it may not be very appealing. Covering your tank's bottom glass or acrylic with a piece of Black ABS Plastic will add a layer of protection between your rocks and the glass, and also gives a much more pleasing appearance. 

  • 100% Reef Safe
  • Aesthetically Pleasing
  • Added Protection
  • Easily Cut To Size
  • Textured or Smooth Sides


We have used black ABS plastic on many bare-bottom tanks and enjoy the look it gives much more than a traditional sandless aquarium. Many reefers use sand on the bottom of their aquariums but in the long run the small particles of sand can cause issues with trapping nutrients, obtaining the proper amount of flow, and even decreasing the life of your pumps and other equipment, which are some of the issues you do not need to worry about with a bare-bottom aquarium. In most cases, the weight of the rock will hold the plastic sheet in place, but a small amount of aquarium safe silicone can help seal the plastic to the bottom keeping detritus and other foreign objects from getting trapped under the plastic.

Product Questions

I’m thinking about doing a bare bottom in my red sea reefer 250 deluxe. What are the inside dimensions to cut a piece of 1/8 inch plastic?
Question by: Laurel on Feb 1, 2020, 11:41 PM
Hey there,

The internal dimensions would be 34"x18.5".

Take care
