How Fish Stores Filter and Water Change 110 Aquariums: Inside a Professional Fish Store System
How Fish Stores Filter and Water Change Tanks
If you've ever walked into a large aquarium store and wondered how they maintain dozens or even hundreds of fish tanks at once, you're not alone. Water changes and filtration can be a challenge for even a handful of aquariums, so how do professional fish stores keep entire walls of tanks clean, healthy, and crystal clear?
In the latest DALUA Fishroom video, we get exclusive access behind the scenes at Beyond Aquariums to see exactly how their large-scale aquarium system operates. The store runs approximately 110 fish tanks using a combination of centralized filtration, automated water changes, and built-in safety features designed to minimize maintenance while maximizing fish health.\
Why Fish Stores Need Automated Systems
Performing water changes manually across dozens of aquariums would take an enormous amount of time each week. Professional fish stores need systems that are reliable, efficient, and capable of maintaining consistent water quality every day.
In this video, DALUA Fishroom explores how Beyond Aquariums has reduced maintenance workload through smart plumbing design and automated water management. The result is a cleaner, safer, and more efficient system that allows staff to spend less time carrying buckets and more time caring for fish and serving customers.
The Power of Centralized Filtration
Rather than running individual filtration systems for every aquarium, many professional fish stores connect groups of tanks to a central filtration system.
A centralized approach offers several benefits:
- Easier maintenance
- More stable water parameters
- Reduced equipment costs
- Improved consistency across multiple aquariums
- Better filtration capacity
The video showcases how waste is removed from multiple tanks and processed through filtration equipment before clean water returns to the system. This creates a scalable approach for managing large numbers of aquariums under one roof.
Automated Water Changes
Regular water changes remain one of the most important aspects of aquarium maintenance.
The system featured in the video automates much of this process, allowing old water to be removed and replaced without the need for manual siphoning from every individual tank. Automated water changes help maintain stable water quality, reduce nitrate accumulation, and ensure healthier conditions for fish.
For fish stores managing hundreds or even thousands of livestock, automation can dramatically reduce labor while improving consistency.
What Happens When the Power Goes Out?
One of the most interesting sections of the video focuses on system safeguards.
Large aquarium systems must be designed to handle unexpected events such as power failures. Poorly designed systems can overflow, drain tanks, or create major issues when pumps stop operating.
Beyond Aquariums has incorporated overflow protection and other safeguards into its design to help protect both livestock and equipment. These preventative measures are often overlooked by hobbyists but are critical when operating a large-scale fish room or retail store.
Lessons Hobbyists Can Learn
While most aquarists won't be maintaining 110 tanks, there are valuable takeaways from professional systems:
Design for Easy Maintenance
The easier a tank is to maintain, the more likely regular maintenance will be completed consistently.
Plan for Emergencies
Overflow protection and power outage planning can prevent expensive mistakes.
Focus on Water Quality
Successful fish stores rely on stable water conditions rather than constant troubleshooting.
Automate Where Possible
Simple automation can save time and improve consistency, especially in fish rooms or breeding setups.
