Transforming a problematic aquarium into a stunning reef slope masterpiece, this project showcases meticulous aquascaping and innovative engineering. The original setup suffered from insecure rockwork and exposed plumbing, presenting a perfect opportunity for a complete overhaul. This build focuses on creating a visually appealing and functional environment, addressing both aesthetic and practical concerns. The challenge of the aquarium's tall, narrow dimensions was ingeniously overcome through careful planning and the strategic use of supporting structures.This detailed account documents the entire process, from the initial design concept focusing on a habitat-rich reef slope, to the construction of a robust, concealed support system using acrylic, marine sealant, and stainless steel. The creation of impressive rock formations using various cements and adhesives is explored, highlighting the techniques used to achieve a natural, flowing aquascape. Discover how strategic placement of a powerhead ensures optimal water circulation and waste management, culminating in a beautiful and biologically sound reef environment.

Restarting and Reimagining the Aquarium
This project involved a complete restart of an existing aquarium. The previous aquascape lacked secure rocks and featured unusable, exposed plumbing. This presented the perfect opportunity for a fresh design.
The goal was to create a visually appealing and functional reef slope environment. The aquarium's tall, narrow dimensions influenced the design, emphasizing the need for effective equipment concealment.
Engineering the Aquascape
The aquascape was meticulously engineered using carob C arches and various cements. The design aimed for an open, yet habitat-rich environment suitable for fish and coral.
A sturdy support structure was essential. Six pieces of one-inch thick, three-inch wide acrylic were assembled into an L-shaped lattice and secured to the aquarium's back and bottom using silicone and 5200 marine sealant, further reinforced with 316 stainless steel bolts.
Creating Realistic Arches and Flow
Epoxy putty, super glue, and E-marco cement were used to create large, seemingly impossible arches, ensuring structural integrity.

Careful consideration was given to the natural flow of the aquascape, creating a visually interesting, continuous line that draws the eye across the aquarium.
Habitat Design for Specific Inhabitants
A large cave system was incorporated at the bottom for an eel, creating the illusion of a single, continuous tunnel.

The design elements are cleverly positioned to offer hiding spaces and natural swimming paths for different fish.

Water Flow and Filtration
A powerful powerhead strategically placed behind the main structure directs water flow downwards, then outwards towards the front.

This creates an upwelling effect, enhancing water circulation and preventing waste buildup in hard-to-reach areas. The flow also directs waste towards the overflow for filtration.
Conclusion: A Successful Custom Aquarium Build
The engineered hardscape offered flexibility in creating diverse habitats. The final result is an aesthetically pleasing and functionally sound aquarium.

The project successfully addressed the owner's previous concerns about visibility and provided ideal living conditions for the eel and other planned inhabitants. The natural flow patterns mimic the fish's natural behavior.
