Grow Your Own Fish and Vegetables Right in Your Backyard
Aquaponics is the simplest way to produce fresh food at home — fish fertilize the plants, plants clean the water, and your only job is feeding the fish once a day. This site has everything you need to get started and keep growing.
Where Do You Want to Start?
Whether you're still trying to understand what aquaponics is or you're ready to build your first system, start here.
New to Aquaponics?
Start with the nitrogen cycle, system types, and what makes aquaponics different from hydroponics — or a regular fish tank. Plain-language guides, no assumed knowledge.

IBC Tote Aquaponics System
The most popular backyard aquaponics build. A 275-gallon IBC tote split into a fish tank and flood-and-drain grow bed. Produces 30–50 lbs of vegetables and 10–15 lbs of tilapia or catfish per year.
View the free plan →55-Gallon Barrel System
The ideal first aquaponics system — low cost, small footprint, and forgiving for beginners still learning water chemistry. Fits on a deck or patio. Perfect for learning the fundamentals before scaling up.
View the free plan →Greenhouse Aquaponics System
A four-season food production system that runs year-round in any climate. Double the output of an outdoor IBC system. Grow tomatoes, herbs, and greens through winter with insulation and a tank heater.

The nitrogen cycle is what separates a productive aquaponics system from an expensive fish tank. Here's the 30-second version.
Less Water Than Soil Gardening
Water recirculates through the system continuously. You only top off for evaporation — no watering plants, no water changes needed in a healthy system.
More Food Per Square Foot
Plants grow in a nutrient-dense solution without competing for soil. Lettuce takes 4–6 weeks from seed to harvest — faster than any garden bed.
Food Sources From One System
A single 275-gallon IBC system produces both vegetables and fish. Tilapia reach harvest weight in 6–9 months — 10–15 lbs of fish per year from a 4×4 ft footprint.
Weeding, Tilling, or Synthetic Fertilizers
Fish waste is the only fertilizer your plants need. No soil means no weeds, no tilling, and no digging. Once your system is cycled, it mostly runs itself.
Essential Gear for Any Aquaponics System
Four things every system needs regardless of size. These are the products we actually use — linked to current Amazon pricing.
API Freshwater Master Test Kit
Tests ammonia, nitrite, nitrate, and pH — the four numbers that tell you everything about your system's health. You cannot manage an aquaponics system without this. Tests up to 800 times.
VIVOSUN Commercial Air Pump
Dissolved oxygen is critical for both fish and the nitrifying bacteria that make the whole system work. Quiet, reliable, and sized correctly for systems up to 100 gallons.
Active Aqua Submersible Pump
Reliable 400 GPH pump to move water from the fish tank to grow beds. Easy to install, easy to clean, and sized correctly for most IBC tote and barrel builds. Low power draw.
Hydroton Expanded Clay Pebbles
The best grow media for aquaponics — pH neutral, excellent drainage and aeration, reusable for years. One 50L bag fills a standard flood-and-drain grow bed.
