About Aquaponics Filter

Aquaponics Filter publishes practical guides for small and desktop aquaponics systems, the kind that sit on a desk or a kitchen counter with a few gallons of water, a handful of small fish, and a grow bed of herbs or greens on top. The guides cover how those systems filter their own water, which fish and plants suit them, and how to set one up and keep it stable.

Why small systems

Small systems get less attention than backyard and commercial aquaponics, and they leave less room for error. In a few gallons of water, ammonia rises faster, temperature swings harder, and a single day of overfeeding shows up in the test results. Advice written for systems holding hundreds of liters often scales down badly, so the guides here start from the small end and stay there.

What the site covers

The guides are organized in four sections. Filtration covers the nitrogen cycle and grow media, Plants covers plant choice and nutrient deficiencies, Fish covers species and feeding, and Setup covers cycling, water testing, and troubleshooting. Longer pieces on single questions are listed under Articles.

How the guides are written

The guides follow widely used aquaponics and aquarium practice, and they cite the FAO's technical manual on small-scale aquaponic food production where its figures apply. Water chemistry targets, cycling times, and stocking levels are given as ranges, because they depend on the fish, the plants, the room temperature, and the water you start with, and the guides point out where common practice varies.
