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 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 […]

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 […]

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 […]

Feeding your Food: Plant Nutrient Deficiency and Toxicity in Aquaponics Systems

The major benefit of aquaponics is being able to harvest the most delicious and fresh ingredients just in time for your next meal. But if you want the tastiest and healthiest ingredients possible, you will want to insure that your plants are being well fed first! In order to do that you need to avoid nutrient […]

pH and Water Hardness in your Aquaponics System

Most of us aquapons know that the health of all the creatures in our systems (fish, plants, worms, and bacteria) depends on proper pH. We also know that we are targeting pH in the 6.8 to 7.0 range but that we don’t have to worry about adjusting it until it goes down to 6.4 or […]
