Why AquaHaus
Every serious reef keeper knows the drill: you need a handful of frag plugs or an encrusting disc, and the only options are a slow, expensive import or a generic batch from a local fish shop that doesn't quite fit your setup. There wasn't a South African source built specifically for this hobby, so we built one.
AquaHaus designs and 3D prints reef hardware to order: frag plugs, encrusting discs, frag racks, travel holders, and accessories, printed here in South Africa and shipped in days rather than weeks. No shipping container to wait on, no import duties baked into the price, and no minimum order of a thousand identical plugs.
The team behind it
AquaHaus is run by a small team of dedicated reefers. That means the same people who design the parts, run the printers, pack the orders, and answer your emails also keep reef tanks themselves. We know what a frag plug goes through: glued, set into the rock, moved between racks, and occasionally knocked by an overenthusiastic clownfish.
AquaHaus trades under DobixHub (Pty) Ltd (Reg. 2026/442847/07), a registered South African company.
What makes a good frag plug
A frag plug has a simple job, but it has to get a few things right. These are the ones we design around.
It stays put
A plug that floats takes your frag with it. Every AquaHaus plug is weighted and fit-tested so it sinks and stays where you put it.
It gives glue something to grip
Frags are glued to the plug, and plugs are often fixed into the rock with epoxy. The printed surface gives both a texture to hold on to, so the frag stays on the plug and the plug stays in the rock.
It's safe in your tank
Every piece is printed in PETG, a stable plastic researchers choose for use in seawater.
How it's made
Every piece is FDM 3D printed in PETG, a material widely used across the reef-keeping hobby for its durability and its stability in water. Nothing sits in a warehouse as finished stock; each order is printed after you place it, which means less waste, faster iteration on new designs, and the flexibility to tweak a shape based on what the reefing community actually asks for.
Because everything is made to order in small batches on desktop printers rather than injection-moulded by the pallet, AquaHaus won't always be the cheapest option on the shelf. The trade-off is hardware designed by someone who actually uses it, made close to home, without the six-week wait.
Where we're headed
The current range covers frag plugs, encrusting discs, frag racks, travel holders, and fitting accessories, and it keeps growing. As the range grows, the goal stays the same: useful, well-made reef hardware, designed with the local hobby in mind, not repackaged for it.
