IceCap 7 Gallon Trimless Cube Glass Aquarium
The IceCap 7 Gallon Trimless Cube Aquarium (SKU: IC-AQCB7) is an authentic, artisan-crafted glass enclosure distributed by CoralVue to redefine compact desktop nano aquarium displays. Standard small tanks are often configured as flimsy plastic bowls or cheap injection-molded acrylic arrays; while functional, these profiles easily scratch, warp perspective, and degrade clarity over time. The IC-AQCB7 corrects this restriction completely by organizing 7 gallons of primary water volume inside an identical 11.8-inch square dimension matrix. This clean geometric format gives freshwater aquascapers and micro-pico specialists an exceptional canvas to establish precision scale and multi-dimensional movement on a miniature scale that standard rectangular nano tanks cannot match.
Every aspect of this rimless profile is designed to minimize visual distraction. All four primary viewing faces are engineered from premium 5mm low-iron glass. By removing the heavy iron-oxide impurities found in standard float glass, the panels remain completely transparent, showcasing the true color values of your flora, fauna, and aquascaping elements. The seams are joined using high-performance clear German silicone, creating a borderless appearance. Because the tank is a balanced square, it allows standard clamp-on or pendant-style nano LED fixtures to provide uniform PAR lighting distribution straight down to the substrate level. This makes it a perfect foundational platform for growing demanding dwarf mosses, maintaining low-energy micro layouts, or raising delicate ornamental shrimp strains.
Key Features:
Maximized Dynamic Landscaping: Seamless 1:1 footprint enables you to build miniature central stone structures or tiny driftwood pillars that can be viewed cleanly from the front, left, or right sides.
Safe For Sensitive Micro-Shifting: The rimless design allows effortless positioning of emergent hardscape elements like tiny twig branches or micro volcanic rocks breaking past the water line.
Integrated Structural Stress Relief: Arrives with a factory-bonded, dense foam base mat that prevents microscopic glass imperfections from developing stress fractures over time.
Note: This open-top aquarium includes the standalone low-iron glass tank frame and a pre-installed self-leveling mat. Mini filter pumps, lighting fixtures, and decorative hardscapes are sold under separate product categories.

Warranty
CoralVue, Inc. hereby guarantees this product to be free from defects in material and workmanship for a period of:
- 1 Year
Warranty is activated on the date of purchase.
This Standard Limited Warranty applies and is limited as follows:
- To the product only as long as it remains in the possession of the original purchaser.
- To the product that has not been subject to accident, misuse or abuse.
- To the product that has not been modified, altered, defaced, or had repairs made or attempted by other than CoralVue, Inc.
- That CoralVue be immediately notified in writing within ten (10) days of first knowledge of defect by owner or his agent.
- That CoralVue, Inc. shall be given first opportunity to make any repairs, replacements or corrections to the defective construction within a reasonable period of time.
- Under no circumstances shall CoralVue and/or the Manufacturer be liable by virtue of this warranty or otherwise for damage to any person or property whatsoever for any special, indirect, secondary or consequential damages of any nature however arising out of the use or inability to use because of the product defect.
Instructions:
- Carefully unbox your IC-AQCB7 tank on a completely flat, clear workspace. Do not remove the black self-leveling foam mat permanently bonded to the bottom glass panel.
- Position the aquarium in its final location on a dedicated, level, sturdy desk, counter, or office table. Warning: Filled with water and gravel, this nano setup weighs nearly 70 lbs and must sit on a surface that provides continuous, unbroken support across its entire 11.8-inch square base. Placement on unstable furniture voids factory warranty coverage.
- If utilizing an internal micro corner filter or external nano canister, install your plumbing paths or filter frames along the back pane to preserve clean front-facing sightlines.
- Arrange your specialized soil, micro-stones, and nano-driftwood carefully inside the dry tank. Pro Tip: Because the glass is rimless, use plastic aquascaping pinsettes to prevent accidental glass damage during hardscape positioning.
- Place a small sheet of plastic wrap or a clean paper towel directly over your substrate to diffuse the water stream, then slowly siphon or pour in your water to avoid disturbing your design.
- Fill the water level to within 0.5 inches of the polished upper rim, install your rim-clamping desktop LED light fixture, turn on your filtration system, and check all seams to ensure smooth operation.
Pro Tips:
- Utilize an Auto Top-Off System to Prevent Salinity and Parameter Fluctuations. Because nano cube enclosures utilize an open-top, rimless format, evaporation occurs quickly. In a 7-gallon system, losing even a small fraction of water to the air can cause a fast concentration of dissolved minerals, plant fertilizer salts, or a sharp spike in salinity (if used as a saltwater pico reef). Installing a compact auto top-off (ATO) system inside your filtration loop keeps your water line stable and prevents your filter pump from running dry and burning out.
- Always Double-Check Surface Leveling Across Both Horizontal Axes. Rimless glass enclosures are uniquely sensitive to twisting stress when placed on home office desks or nightstands. Because a cube distributes its weight symmetrically, if the surface sags or tilts toward one corner, gravity will twist the clear silicone seams unevenly. Before adding any water, rest a bubble level directly across the top polished edges from front-to-back and left-to-right. Use structural shims beneath the furniture legs rather than directly under the glass to secure a perfectly level layout.
- Stock Exclusively with Micro-Fauna to Maintain Biological Balance. Due to the 7-gallon volume limits, this environment is best suited for small, low-bioload micro-fauna. Focus the visual scale of your aquascape around colorful micro-invertebrates like ornamental dwarf shrimp (such as Cherry or Crystal Red variants) and tiny nano-schooling fish species like Chili Rasboras or Endler's Livebearers. A small group navigating this deep landscape delivers an immense sense of scale while keeping parameters highly stable.
