What Early Fish Culturists Learned About Hatching and Rearing Fish
Long before modern hatcheries, a small group of 19th-century practitioners worked out how to hatch fish eggs artificially through costly trial and error. Their failures were as instructive as their successes.
Deep Water Culture and the Water Culture Method for Growing Plants Without Soil
Water culture, the practice of growing plants with their roots suspended in nutrient solution, has a longer and more complicated history than most growers realise. Here is where it came from and what actually makes it work.
What the UVI Aquaponics Trials Revealed and Why It Matters
James Rakocy and his team at the University of the Virgin Islands spent decades refining a commercial-scale raft aquaponics system. Here is what they measured, what they found, and what it means if you are growing at home.
Troubleshooting Nutrient Deficiencies in Aquaponics Plants
Iron, potassium and calcium are the nutrients most likely to run short in an aquaponics system. Here is how to spot the signs and correct each one safely.
Growing Leafy Greens and Herbs in Your Aquaponics System
Lettuce, basil, spinach and other leafy greens are the natural starting point for aquaponics growers. They grow fast, suit the nutrient profile of fish effluent, and reward you with harvests while you are still learning the system.
Working Out the Right Fish to Plant Ratio for Your Backyard System
Getting the balance between fish and plants right is the central design challenge in aquaponics. This guide explains the feeding rate ratio and stocking density in plain terms so you can size your system from the ground up.
Choosing Fish Species for Your Home Aquaponics System
The fish you choose will shape everything else in your system. Here is what you need to know about temperature tolerance, growth rates, and which species suit a warm or cool backyard setup.
Building and Tuning a Bell Siphon for a Flood and Drain Bed
A bell siphon automates the flood and drain cycle in a media bed with no timers or electronics. Here is how to size one, put it together, and fix the two problems that trip up almost everyone.
Cycling a New Aquaponics System Before Adding Fish
Before fish can thrive, your system needs a living colony of bacteria to process their waste. Cycling takes weeks, not days, and getting it right makes everything else easier.
Testing and Managing Water Chemistry in Your Aquaponics System
Understanding pH, ammonia, nitrite and nitrate is the difference between a thriving aquaponics system and a disaster. Here is what to test, when to test it, and what to do when the numbers are off.
Media Beds: Choosing Grow Media and Bed Depth
Expanded clay, pea gravel, blue metal or something else? This guide walks through the key choices for media bed fill: particle size, weight, pH safety and why 300mm depth is the number that matters.
Choosing and Sizing a Fish Tank for Your Aquaponics System
Tank shape, depth, volume and material all affect fish health and water quality. Here is what to look for when choosing or sizing a fish tank for a backyard aquaponics system.
Building a Barrel-Based Aquaponics System
Food-grade plastic barrels can be cut and plumbed into a fully functional fish tank and grow beds with basic tools. Here is how to do it, in order, from barrel selection through to filling with gravel and water.
Choosing a Site and Setting Up Your First Backyard Aquaponics System
Before you buy a tank or a pump, you need to walk your yard and ask a few honest questions. Getting the site right is the decision that shapes everything else.
