AquaVoxel / Modular Frag Rack System

AquaVoxel Modular Frag Rack System

The flagship AquaVoxel system — engineered for load, flow, and expansion, not assembled from whatever fit in a mold.

AquaVoxel Std8 plates stacked in all five finishes, with plugs and legs: Coralline Purple, Seafoam Teal, Algae Green, Abyss Black and Pelagic Blue
STD · CORALLINE PURPLE / SEAFOAM TEAL / ALGAE GREEN / ABYSS BLACK / PELAGIC BLUE

An open-lattice frag rack engineered for load, flow, and expansion — not assembled from whatever fit in a mold. Every tile, plug, and connector is dimensioned against the last, so the system scales without compromise.

  • Open trihexagonal latticeMinimal mass, maximum flow-through — won't shift on substrate or fight your water movement.
  • Twist-lock plug interfaceQuarter-turn engagement, rated to hold against current and livestock contact without adhesive.
  • Precision friction-fit legsTuned clearance for tool-free installation and removal — no glue, no wear on the interface.
  • Works with the plugs you ownStd8, LG6, LG14, XL10 and XL26 sockets take standard 3/8-inch (9.5 mm) stem plugs, so you can switch one plate at a time. Will my plugs fit?
  • Pointed legs that sink inPointed legs push down through sand or gravel instead of sitting on top of it, so plates stay level, and the tips rest on the glass with open channels underneath. Legs come in 25 to 85mm; longer legs are available by custom order for deep sand bed (DSB) systems.
  • Sealed N52 magnetic mountsNeodymium magnets sealed in watertight PETG hang any plate on the glass as a shelf.
  • Modular connector platesExpand the array at any shared corner without replacing existing tiles.
  • Corner plates for every sizeA square corner plate and one 3-way connector run a rack along two walls of the tank. Corner plates
  • Double F tier bracketsStep plates up 20mm at a time, offset so no rack ever sits over the tier below. Tiering
  • One system, six platesSix plates on four footprints: the Nano8 takes eight 19.05mm plugs, the Std8 eight 25.4mm, the LG6 six 38.1mm, the LG14 fourteen 25.4mm, the XL10 ten 38.1mm and the XL26 twenty-six 25.4mm. Every plate has the same leg bosses, so one set of legs fits them all. Plates join their own size; LG6 and LG14 mix in one rack, and so do XL10 and XL26. Std, LG and XL plates share one set of connectors; the Nano8 runs its own smaller plugs and connectors.

Unlike standard 3D printed frag racks, AquaVoxel plates are constructed from reef-safe PETG — chosen for its superior water resistance and long-term durability in saltwater environments. A stack of 304 stainless-steel discs is permanently sealed inside the plate's core, so the rack sinks and holds position with zero metal-to-water contact for complete reef safety.

All five stock finishes ship the same week. Want a color of your own? We'll make your rack in any color you like, in reef-safe PETG. Because a custom color means sourcing a spool just for your order, custom orders carry a small setup fee and a small minimum order. Send a hex code, Pantone, or a link to a specific PETG filament and we'll confirm it's available from a brand we trust — then sourced, made and shipped, typically within 7–10 days.

SIDE BY SIDE

How AquaVoxel compares.

AquaVoxel against eggcrate or DIY racks and flat acrylic or standard 3D-printed racks. Read the full breakdown →

FeatureEggcrate / DIYFlat acrylic / standard printsAquaVoxel
Frag securityLoose fit; plugs tip over.Most rely on gravity; snails and strong flow can knock frags loose.Zero-drop 90° twist-lock.
Water flowGrid traps hair algae and detritus.Solid slab blocks flow and creates dead zones.Open hexagonal framework water passes through.
Substrate impactPVC or acrylic legs cover sand patches.Rests flat on the sand, trapping detritus underneath.Pointed legs sink through sand or gravel to the glass, so plates stay level.
Magnet safetyNo mounting option.Quality varies; coated magnets can crack and rust over time.N52 magnets fully sealed in watertight PETG.
ScalabilityCut new pieces; flimsy support.Mostly fixed sizes that don’t link together.Same-size plates link at every corner, from a Nano8 array to an 8 ft raceway.
Plug fitOnly whatever hole size you cut.Fixed holes; tight fits can snap fragile coral bases.Takes standard 3/8-inch plugs; AquaVoxel plugs clip down to fit standard racks.
Corners & tiersCut and stack pieces by hand.Usually one flat level; tank corners left empty.Corner plates for every size, and Double F tiers with no rack over the tier below.
SIX PLATES, ONE LEG SYSTEM

Nano8 to XL26, one set of legs.

Six plates on four footprints, each sized to its plugs: the Nano8 holds eight 19.05mm plugs and the Std8 eight 25.4mm; the LG6 holds six 38.1mm and the LG14 fourteen 25.4mm on the same footprint; the XL10 holds ten 38.1mm and the XL26 twenty-six 25.4mm on the largest footprint. The leg bosses are the one thing every plate has in common, so the same legs fit every size. The XL plates carry a deeper six-disc ballast pocket to keep their larger footprint firmly on the bottom.

Plates join their own size. Link Nano8 plates into an endless Nano array, or Std8 to Std8. The LG and XL each come in two versions on one footprint, so you can mix them in one rack: set LG6 and LG14 side by side, or XL10 and XL26, and hold 38.1mm and 25.4mm plugs in a single array. Std, LG and XL plates all use the same connectors; the Nano8 has its own. Every size also has a matching corner plate.

THE HARDWARE

Every AquaVoxel plate builds from the same small kit.

No proprietary fasteners and no single-use pieces. Universal legs fit every plate size. Plugs and connectors come in two families: one for the Std, LG and XL plates, and a dedicated set for the Nano8. Every part comes in every finish.

AquaVoxel frag plugs: 19.05, 25.4 and 38.1mm 01 — FRAG PLUGS

Three sizes, twist-lock fit

19.05mm for the Nano8, 25.4mm for the Std8, LG14 and XL26, and 38.1mm for the LG6 and XL10. Each has a fluted grip band and twists into its socket to lock, then twists and lifts out when a frag is ready to move. Plastic plugs are usually light enough for strong flow to knock loose; the lock means weight no longer matters. PETG also won’t chip or shed grit like low-grade ceramic. The 19.05mm plug fits Nano8 plates only. The textured top gives coral tissue something to grip and encrust onto, and it holds epoxy or glue without a pretreat step. Corals draw their calcium from your water, not the plug, so the texture is what counts. No AquaVoxel rack? Clip off the two locking ears and the plug fits any standard frag rack.

AquaVoxel universal legs in 25, 35 and 45mm 02 — LEGS

Universal legs: 25, 35 and 45mm

Pointed legs with a 6mm pin that press-fit into the leg bosses. The point pushes down through sand or gravel instead of riding on top, so the plate stays level. The bosses are identical on every plate, Nano8 through XL26, so one set of legs serves the whole system. Mix lengths to level a plate across sand, rubble or rockwork, with no glue and no tools.

AquaVoxel full-size and Nano 2-way and 4-way connectors with the included 20, 30 and 40mm connector legs 03 — CONNECTORS

Join plates at shared corners

A 2-way connector joins two plates edge to edge; a 4-way connector locks four plates at a shared corner. Posts drop into the leg bosses from below, and a matching connector leg (20, 30 or 40mm) plugs into the connector. Connector legs run 5mm shorter than the universal legs, so a joined corner stands level with a 25, 35 or 45mm leg. Full-size and Nano connectors are sized to their own plate families, and plates join plates of their own footprint.

Two AquaVoxel pin punches in Abyss Black and Seafoam Teal 04 — PIN PUNCH

Clear a boss without prying

A small punch sized to the leg bosses, with a wide 18mm pad your fingertip can press on. One pushes out a leg. To take a plate off a rack, set one on the connector post at each end of the seam and press both at once, so the plate comes away level without stressing either post. Every kit includes two.

Three AquaVoxel plugs locked into white foam shipping floats 05 — SHIPPING FLOATS

Ship frags upright, every time

A 25mm foam float with a keyway cut through it to match the plug stem. Push a 25.4 or 38.1mm plug in and give it a quarter turn to lock. In a water-filled bag the float rides at the top and the coral hangs below it, so the frag stays submerged however the box lands and never hits the bottom of the bag. At the other end, twist the float off and the plug goes straight into a rack. Packs of 20, for frag sellers and swaps.

A Std8 corner plate joined to two Std8 plates 06 — CORNER PLATES

A square corner for every size

Sold as a corner kit with its plugs and a 3-way connector. Nano8, Std8, LG6, LG14, XL10 and XL26 corners each match the short end of their plates, so a rack runs along two walls without a gap. See how corners go together →

AquaVoxel 3-way corner connectors, full size and Nano 07 — 3-WAY CONNECTOR

Locks three plates at a corner

One connector joins the corner plate and the plates on both sides where their corners meet, with a single connector leg right under the junction. Full size for Std, LG and XL plates, plus a Nano version for the Nano8. Packs of 4.

Four AquaVoxel Double F tier brackets in Seafoam Teal 08 — DOUBLE F TIER BRACKETS

Step up 20mm with no overlap

Each bracket grips the edge of one plate and holds the next 20mm higher and off to the side, using the same groove as our magnetic mounts. Two per tier, up to three tiers. Fits Std8, LG and XL plates. Packs of 4. See tiering →

AquaVoxel pointed legs from 25 to 85mm 09 — TIER LEGS

Pointed legs up to 85mm

Longer legs, 50 to 85mm in 5mm steps, for tiered racks standing on the sand bed. Same pointed design and the same pin as every AquaVoxel leg. Packs of 16.

SCALE THE ARRAY

Expand without replacing what you already own.

Connectors lock adjoining AquaVoxel plates together through their leg bosses, so a rack grows one plate at a time, in any finish, without disturbing plates already seeded and settled.

Mix plug sizesAn XL10 and an XL26 share a footprint, so 38.1mm and 25.4mm plugs sit in one rigid array. The LG6 and LG14 mix the same way. Plates join their own footprint only: Nano8 to Nano8, Std8 to Std8.
CORNER PLATES

Turn the corner without leaving a gap.

Every plate size has a matching square corner plate. It sits in the corner of the tank, a plate butts against each of its inside edges, and one 3-way connector locks all three together where their corners meet. The rack runs along two walls as one rigid piece, on legs or on magnetic mounts.

A corner for every plateLeft to right: Nano8 Corner (4 × 19.05mm plugs, 58mm square), Std8 Corner (4 × 25.4mm, 77.4mm), LG6 Corner (4 × 38.1mm, 90.1mm), LG14 Corner (9 × 25.4mm, 90.1mm), XL10 Corner (8 × 38.1mm, 134mm) and XL26 Corner (16 × 25.4mm, 134mm). Each is the size of its plates’ short end and uses the same legs and connector legs as the rest of the rack. LG corners join LG6 and LG14; XL corners join XL10 and XL26.
DOUBLE F TIER BRACKETS

Tier your rack without shading it.

A Double F bracket slides onto the edge of one plate and holds the next plate 20mm higher, set off to the side. No AquaVoxel rack sits over the tier below it, so every frag gets full light, lower corals have room to grow, and detritus from above falls past the tier below instead of onto it. Use two brackets per tier, up to three tiers, on Std8, LG and XL plates.

FOR FRAG FARMS & DEALERS

From one plate to a full production raceway.

Every AquaVoxel plate locks to its neighbors at the corners, so a whole tank becomes one rigid, level rack with an even grid of plugs from wall to wall. Add plates as the farm grows without moving a single frag that’s already settled.

Thirty AquaVoxel Std8 plates in Abyss Black, joined into one 922 by 387 mm rack and stocked with 240 frags, in a large shallow frag tank
30 Std8 plates · 240 frags · 1000 × 500 × 250mm frag tank. Rendered from our production files.
01 — TWIST-LOCK PLUGS

Pick orders without disturbing the tank

Plugs lock with a quarter turn and come out with a twist and a lift. No glue in the socket, no prying, no knocking the frag next door. Staff can pull a sold frag in seconds and leave its neighbors untouched.

02 — SEALED BALLAST

Racks that stay where you put them

A 304 stainless disc stack is sealed inside every plate, so racks sink and hold position without rock, zip ties or suction cups, and no metal ever touches your water. The XL10 and XL26 carry a deeper six-disc pocket for their larger footprint.

03 — ONE RIGID ARRAY

Locked at every shared corner

4-way and 2-way connectors join plates through their leg bosses, so the array can’t drift apart or shift in strong flow. Expand at any edge, one plate at a time.

04 — DENSITY

More frags per square meter

The LG14 holds fourteen 25.4mm plugs on a 166.3 × 90.1mm plate, about 930 plugs per square meter of rack and nearly 40% more than the Std8. The XL26 goes further, at about 965 per square meter. LG6 and LG14 share a footprint, so both can run in the same grid, and so can XL10 and XL26.

05 — LEVEL ON ANY BOTTOM

Pointed legs from 20 to 85mm

Universal legs (25, 35, 45mm), connector legs (20, 30, 40mm) and tier legs up to 85mm level a rack over sand, gravel, rubble or bare glass; the pointed tips sink in instead of riding on top. Longer legs are available by custom order for deep sand bed (DSB) systems. The open lattice lets flow and light reach every frag and lets detritus fall through.

06 — COLOR-CODED STOCK

Sort inventory at a glance

Five reef-safe PETG finishes let you assign colors by species, grower, price tier or sale status. Custom colors are available for larger orders.

07 — PLUGS THAT FIT ANY RACK

Your customers aren’t locked in

Sell frags on AquaVoxel plugs with confidence. If a customer doesn’t own an AquaVoxel rack, they simply clip off the plug’s locking ears and it fits any standard frag rack.
