There are many reasons to ensure the temperature of your DIY aquaponic tank, pond or fountain are optimal.  And by optimal we mean suitable for the type of fish you house and for the current activity of your fish.

 

Dependent on the breed of fish you have you need to ensure the temperature they live in is correct.  Too hot or too cold water can cause shock to a fish and they can possibly die.  Another factor to consider is the activity you fish is involved in.  Sounds odd, right?  What activity other than swimming around do fish partake in?  But, there are a few reasons why water temperature needs to be adjusted.

 

o   Breeding season – depending on breed of your fish, between 10°C (50°F) and 12°C (54°F)

o   Non-breeding season – again depending on breed of your fish – around 23°C (74°F)

o   Air Supply – the hotter the temperature, the less oxygen in the tank – so an aeration system may be necessary

o   Breed of Fish – as above, the temperature and other factors grossly differ from breed of fish to breed of fish

 

These all require a very different set temperature and to gain the best results should be monitored and kept constant.

 

We all understand that water temperature will fluctuate dependent on the time of day or night, on the season and on the position of the reservoir (i.e. is the tank receiving afternoon sun or heavy shade at a particular time of the day?). However, if you could regulate the temperature you could be assured of not only preserving the longevity of your fish but saving yourself a bucket full in replacement costs.  Moreover, we all know how expensive the set up, equipment and not to mention the fish can be for a DIY aquaponic system.

 

So, what do you need to ensure optimal temperature in your aquaponics Aquarium?

 

What you need is an Aquarium Heater system.  To help you along in the perfect fit for your setup, we have put together our top 5 best Aquarium Heaters and salient features (good and bad - although there weren’t many bad reviews).
