The Effects of a UV Sterilizer on an Aquaponics System

by Joanne Bell, Grow Lab Manager, The Aquaponic Source

We had an unfortunate invasion of planktonic algae (floating microscopic plants) in one of our grow lab systems. Unlike other forms of algae that cling to surfaces, this type is free-floating in the water. In lakes and ponds, some planktonic algae is considered beneficial. But too much can […]

Grow Lab Update – Growing in Fabric Bags

If you’ve visited our grow lab anytime since last spring, you would have noticed that we have been doing a lot of experimenting with growing in fabric bags.  Our hypothesis was that they would be great for the following purposes:

Aquaponics – Dual Root Zone

AquaDRThe idea behind this technique is to create a separate area in the top of the root zone where you can boost growth by adding fertilizer (organic, of course!) to the top roots of the plant in a way that doesn’t drain into the water for […]

Aquaponics Grow Lab Update – Aquaponic Elements

One of the main benefits of moving into our facility last year was that we finally have a grow lab.  Back when we were working out of the basement we would experiment with plants and products in our backyard greenhouse system.  The problem was that there was only one fish tank and all the water […]

The Carbonates Controversy in Aquaponics

carbonates in aquaponicsLast May I wrote a post titled “pH and Water Hardness in Your Aquaponics System”. In that post, I explored the relationship between pH movement, alkalinity and KH or carbonate hardness.  Since then, there has been some swirling controversy about the use of carbonates […]

Aquaponics Disaster Preparedness

Boulder FloodTo say this past week has been a tough one for the communities where I live (Boulder, CO) and work (Longmont, CO) would be an extreme understatement.  Record rainfalls causing major floods have forced us all to focus strictly on life’s basics.  Is our home […]

Iron Deficiency in Aquaponics

Please visit our Iron Additions Calculator Page.

The good news – fish waste broken down by bacteria is a surprisingly complete plant fertilizer.  However, aquaponic systems are routinely deficient in a few nutrients  – primarily potassium, calcium, and iron.  We routinely address the potassium and calcium deficiencies by buffering (raising) our system’s pH with compounds […]
