Cliff Series background, cut to your exact size and built from the same mold as our 120" x 36" standard size.

ALWAYS USE INTERIOR DIMENSIONS WHEN MEASURING FOR THIS PRODUCT.
ENTER MEASUREMENTS USING DECIMALS ONLY (ex: 24 1/2" would be 24.5).

We will cut this background to the size you request, please use the interior dimensions of your tank or enclosure. We cut to the nearest 1/8", so please try to be as accurate as possible.

Available in any size, cut from the same mold as our 120" x 36" standard Cliff Series background. This piece reaches thicknesses of about 8" in certain areas, with the same horizontal strata texture as the rest of the line.

DETAILS

Cliff Series brings the layered, horizontal strata of real basalt-style cliff faces from the California desert to a fully custom size, cut from the same mold as our largest standard size. Mount it one way for basking ledges and climbing terrain, or flip it over for a cave-effect layout with deeper hiding spots.

How is it colored?
Unlike our other colors, which use a hand-mixed blend of oxides, sand, and crushed rock, Cliff Series black is made from our straight polymer base. That means no hand-mixing variation between batches, zero color transfer to your hands, and a surface that's highly scratch-resistant and easy to keep clean.

For tanks or enclosures with overflow boxes, unique shapes, or other non-standard features, please call 972-412-7179 — these builds require additional work and care.

WHAT ARE END CAPS?

End Cap Option: What is it, and do you need it?

End caps are designed to prevent you from seeing behind the background from the side view of your tank or enclosure. They're also useful for creating space to place heaters, filters, or other equipment behind the background. They don't take up more space or protrude any further than the background itself. End caps cannot be added after the fact, so decide before you order.

CARE & SETUP
  • If It Arrives Bent: Lay it flat in direct sunlight (or use another heat source) to relax it back into shape before mounting.
  • Attaching: Secure with 100% silicone along the back edges, no full-panel adhesive needed.
  • Cleaning: Rinse with water, or use a stiff nylon brush for anything more stubborn. Remove the background before using medicines like Methylene Blue, which can stain it.
  • New Tank Note: A bit of cloudiness in the days after adding new décor is normal in freshwater tanks and should clear within about 2 weeks. Stick to smaller water changes (around 50% every 7 days, or 25% every 3) rather than trying to rush it, and hold off adding fish until an uncycled tank finishes cycling.
  • Reptile Enclosures: Rated to withstand direct heat up to 200°F. Keep any heat lamp or element that could exceed that from touching the background directly.
  • Color Note: Because black uses our straight polymer base rather than a crushed rock/sand mix, it's more difficult to paint or recolor later if you change your setup.
