1. What's in the Box?

Before you begin, please ensure you have all the components listed below. Lay them out on a flat, soft surface.

CRITICAL STEP: Remove the protective film from BOTH sides of the PVC panels. The panels may look "scratchy" or "foggy" until this film is removed.

2. Assembly Instructions

1
Assemble the Base and Sides

Place the bottom PVC panel on a flat floor. Align the Left and Right side panels with the pre-drilled holes on the base. Use the provided screws to secure them from the bottom up.

Pro Tip: Do not fully tighten the screws yet! Leave them slightly loose (about 90% tight) to allow wiggle room for the back panel.
2
Insert Back Panel & Support Bars

Slide the back panel into the vertical grooves on the side panels. Once seated, install the two horizontal support bars across the front. These bars provide structural integrity for the glass.

Install Top Mesh & Tighten

Place the top mesh frame onto the assembly. Ensure the alignment pegs fit into the holes on the side panels. Once everything is aligned, go back and fully tighten all screws on the base and sides.

4
Door Tracks & Glass Installation

This is the most common area for mistakes.

  • Top Track: This has the DEEPER groove. Install this on the top frame.
  • Bottom Track: This has the SHALLOWER groove. Install this on the bottom lip.

To install the glass: Lift the glass pane UP into the top (deep) track first, swing the bottom in, and gently drop it into the bottom (shallow) track.

Check: If your glass doors fall out, you have installed the Top Track on the bottom by mistake. Swap them around!

Frequently Asked Questions

1. Do I need power tools for assembly?
No, a standard Phillips head screwdriver is all you need. We advise against using power drills as they can crack the PVC if over-torqued.
2. Why are my panels cloudy or scratched?
This is the protective film! Every acrylic and PVC panel has a tight-fitting film on BOTH sides. Please peel it off to reveal the clear/clean surface underneath.
3. Can I stack another enclosure on top?
Yes, Toxirium enclosures are stackable. We recommend using our Stacking Spacers (sold separately) to ensure proper ventilation for the bottom unit's mesh top.
4. The glass doors are hard to slide, why?
Check your tracks. The deep track must be on the top, and the shallow track on the bottom. If debris gets in the track, clean it with a vacuum or cloth.
5. Is the enclosure waterproof?
The PVC material is waterproof and won't rot like wood. However, for bio-active setups, we recommend sealing the bottom seams with aquarium-safe silicone to prevent standing water leakage.
