Aquaponics: Dealing w Diurnal Temperature Swings

Today, IAF explores remediation of effects of large diurnal (between day/night) temperature swings in Aquaponics systems. Small (100 gal and under) systems are particularly vulnerable to quick changes in pH and temperature. Such rapid changes are detrimental to the entirety of the system:

* plants don't metabolize nutrients, leaving nitrates in the water
* water quality suffers,
* fish feed less (produce less ammonia!) and are more prone to infections
* the biofilter (beneficial bacteria, which turn ammonia [fish waste] into nitrites, into nitrates [plant food]) can be injured, leaving ammonia in the water
* ammonia is MORE TOXIC at high temperatures
* DO (dissolved oxygen) drops, because Oxygen is less soluble as temperature increases

All of these factors mean that temperature fluctuations are a BAD THING. In this video, IAF shares this information, and walks through steps taken to remediate the damage in the current heat wave (100'F+ days, 55'F nights):

* Rotating Ice Packs by day, to keep water temperature from escalating too high
* Sadly, may have to use a heater by night, to keep water temp from dropping too low
* Added a bubbler + air stone, to ensure water has enough DO so fish can breathe easy
* Did a PWC (partial water change), which I try to avoid with Aquaponics, to flush out ammonia and ensure fish stay healthy.

In the context of the Grand Solar Minimum, and the highly irregular and increasingly extreme climate, this really speaks to INDOOR GROWING -- AQUAPONICS will produce more reliably in a more controlled environment, without these fluctuations -- which is what we want to ensure FOOD SECURITY.

YOU CAN DO THIS AT HOME! --And you should, to produce clean food for your family. It's that or watch as the food prices continue to increase, and ultimately, the shelves empty completely.

Start taking daily steps NOW towards radical self-sufficiency so that you can thrive in the current Grand Solar Minimum / Little Ice Age.

Discover How Water Temperature Affects Your Aquaponics System

The temperature of the water is crucial in ensuring that your aquaponics system is functioning well. Many enthusiasts monitor the pH levels, plants, fish health but neglect to monitor the temperature of the water. This will result in a system that doesn’t reach its full potential or in some cases, the whole system collapses.

So why is water temperature so important?

Because it affects the amount of oxygen dissolved in the water. The rate which algae multiply is also affected by water temperature. Other factors such as plant photosynthesis, metabolic rates of the fish and the presence of pathogens, parasites and pollutants are all affected by the temperature of the water.

Let’s look at the various types of fish. Understanding the requirements of your fish is important. Some fish like to be in warmer water while some like it cooler. For example, goldfish prefer the water temperature to be below 75 degrees Fahrenheit. Fish like tilapia love being in water that is 70 - 85 degrees. If you’re using trout, you’d do well to keep the temperature below 60 degrees.

Plants are affected when the water is warm too. In warmer temperature, photosynthesis increases. However, beyond 89 degrees Fahrenheit, photosynthesis will stop and decrease. So, if the temperature of your water is above 89 degrees, your plants will not be able to photosynthesize.

Ideally, you want to keep your water temperature in the range of 70-85 degrees Fahrenheit. Or if you’re in the UK – that would be about 22 degrees Celsius to 29 degrees Celsius.

One of the biggest problems many aquaponics owners face is that their fish keep coming to the surface of the water and gasping for air. This means that the fish do not have enough oxygen. With time, the fish will get tired of swimming to the surface and will slowly die. The owners often try to remedy the situation by using more pumps or aerators. Some even try to reduce the number of fish but the problem still persists. Why?

Because the water temperature is too high. Warmer water contains less dissolved oxygen than colder water. It is crucial to have dissolved oxygen in the water for the fish to be happy and healthy. Warm water will raise the metabolic rate of the fish. That means they will require more oxygen. That is bad. Fish that require more oxygen due to higher temperatures but the water has less oxygen due to the same reason. It’s a lose-lose situation.

You want water that has 80 percent saturation of oxygen. If the oxygen levels drop too low, it is almost certain that the fish will die and the whole system will collapse.

Increasing water temperature will also increase the metabolic rate of organisms that live in an aquatic ecosystem. When the metabolic rate increases, so does the demand for dissolved oxygen, along with the increasing rate that organisms go through their life cycle. This increase of life cycle can affect their availability as a food source at specific times when needed.

Hopefully this article has made you aware of the importance water temperature plays. Keep an eye on it and you will be more successful with your aquaponics efforts.
