A Neglected Reef Tank Revival
This 13.5-gallon Fluval Evo saltwater aquarium, over two years old, had been neglected. While maintenance like water changes and filter cleaning were consistent, the tank lacked the attention it deserved in terms of coral additions and arrangement. It remained a largely empty canvas for too long, a project stalled by life's demands.

The initial enthusiasm for creating a thriving reef scape waned, leaving the tank largely untouched. Uncertainty about coral choices and placement further hindered progress, resulting in a lackluster display that fell far short of its potential.

However, renewed interest in the hobby spurred a transformation. The goal shifted to a visually appealing and well-maintained tank; a project worthy of the time and effort invested.

The Transformation Begins: Coral Additions and Placement
Over the past two months, significant progress has been made. New corals have been added, thriving in their new environment. Careful placement and arrangement of existing corals have dramatically improved the overall aesthetic.

The coral selection process involves considering the individual needs of each species, optimizing light and water flow for optimal growth and health. The goal is to create a visually balanced and vibrant ecosystem.

One inhabitant of note is a rather temperamental and shy Da Vinci mocha fish, adding an unexpected element of personality to this small but thriving ecosystem.

Coral Sourcing and Suppliers
Corals were sourced from several suppliers. Frags from the owner's larger 40-gallon tank provided a starting point. Additional corals were acquired from Scott Atos and Salt Critters, both praised for their high-quality offerings.

Scott Atos is highlighted for his extensive collection of fire corals, while Salt Critters is lauded for their reliable online ordering system and consistent top-tier quality. Links to both suppliers are included for those interested.

The owner emphasized the superior quality and service received from both sources, underscoring their reliability and contribution to the tank's transformation.

Tank Tour and Coral Showcase
A detailed tour of the tank showcases various coral species including GSP, Xenia, Zoanthids, hammers, and mushrooms. The owner expresses satisfaction with the growth of some corals, while acknowledging the temperamental nature of others.

The visual appeal of the tank is emphasized, particularly the vibrant colors and healthy growth of the corals. The arrangement aims for a visually appealing and balanced presentation.

A particular focus is on a striking, unidentified coral, which is highlighted for its beauty and unique characteristics, inviting viewers to identify the species.

Equipment and Maintenance
The tank is equipped with an AAT tuna protein skimmer. Maintenance consists of regular filter floss changes, the use of poly filter pads, and careful water changes to prevent algae growth.

The bare-bottom approach aids in maintaining water quality and minimizing algae issues, highlighting the importance of consistent maintenance in preventing problems. Any minor algae growth is addressed promptly with a toothbrush during cleaning.

The overall health and cleanliness of the tank is emphasized, showcasing the effectiveness of the maintenance routine and resulting in a vibrant reef environment.
Conclusion: A Successful Reef Tank Makeover
The 13.5-gallon Fluval Evo reef tank's transformation showcases the rewards of patience, attention to detail, and a commitment to proper maintenance. The initial neglect was overcome through renewed dedication and careful planning.

From a sparsely populated tank to a vibrant reef ecosystem, this project highlights the potential for even smaller systems to thrive with proper care and attention. The successful integration of various corals, along with diligent cleaning and water changes, results in a stunning display.
The project also serves as a testament to the importance of selecting reliable coral suppliers and taking the time to understand the needs of each species for creating a truly thriving and aesthetically pleasing reef tank.
