Find Out How Aquariums Help Grow Vegetation


Aquaphonics is an integration of two cultures: aquaculture (raising fish) and hydroponics (vegetable growing). As part of a fish’s normal protein digestion, ammonia is given off through their gills and urine. Fish’s wastes or uneaten food meanwhile are also given off in the water.

According to Project Leader Chito Sace of CLSU Hydroponics and Aquaponics Technologies says, the fish and prawns are less vulnerable to high levels of nitrites in the water although most plants cannot absorb nitrites. “The presence of bacteria (Nitosomonas and Nitrobacter sp) converts ammonia (NH3) into free nitrogen for the plants,” he says. “The plants filter the water back to the fishtank so the water comes back freshly oxygenated and cleaned of excess nutrients. The bacteria present in the system is completely natural and beneficial.”


He continues, “There are three basic components of aquaponic urban vertical garden: fishtank, filter, and hydroponic (raceway) components interconnected with pipes to become a production system for fish and vegetables in one infrastructure and one body of water. On square-meter area, the system can grow more than 100 hills of leafy vegetables (lettuce, pechay, mustard, water, spinach, and others) and 50-65 tilapia.”



Here are the benefits of Aquaphonics Urban Vertical Garden.


• Empowers households to have direct access to clean foods

• Adds income to households

• Encourages recycling

• Conserves space, water, time and electricity as it uses minimum resources



Here is why the Aquaphonics Urban Vertical Garden is unique from the rest.


· Hydroponics is soilless culture and crops grow in mineral nutrient solutions. Because it is soilless, it can be set up vertically thereby optimizing space.

· Plants that cannot thrive in a particular climate would be possible to grow using a controlled environment system like hydroponics. 

· The system requires above average technical skills to operate and maintain it and sustain the nutrient solution.

· It uses lesser labor, fertilizer, water and energy as it eliminates weeding and minimizes soil-borne diseases.


“As for the CLSU Hydroponics and Aquaponics Technologies, we plan to advance the technology further by establishing a training center,” says Sace. “Our main objective has been to promote the technology as precision and smart farming technique for vegetables production, notably, cucumber, tomato and bell peppers. A training center facility on our site shall further promote the commercialization of technology to various agri-entrepreneurs, i.e. small, medium, and large enterprises.”
