WHAT IS A HOSPITAL TANK?
I don’t like the word quarantine. For this reason I am going to refer to the tank used to treat sick fish away from your main system as a hospital tank. It is important to have a hospital tank to use in tandem with your aquaponics system.
Hospital tanks aren’t new to aquaponics, they have been used in aquarium care for a very long time. The idea behind having a hospital tank is to create a space where you can care for fish outside the normal environment of your system.
HOW TO CREATE A HOSPITAL TANK
The principals for setting up a hospital tank aren’t set in stone, but a few key concepts will help guide you in putting your own together. My suggestion is to have a tank big enough for 20 fish. The average size of your fish in your system will drive how big your tank needs to be. If you have lots of large fish you are going to need a bigger tank. As an example, if you have 20 fish at 1 lb each you would ideally have a 200 gallon tank as your hospital tank. If you are dealing more with fingerling size fish, then you might only need a 50 gallon tank.
Now that we have covered the desired size for your tank it is time to cover the basics of setting it up. The most important part of setting up your hospital tank is to make sure it has proper filtration. If you want to create another media bed and have a second cycled system that is a fine choice. If you would rather use a more traditional aquarium set up that has filtration system built in that is fine too.
Keep in mind that you will need to maneuver more within this system so a tank that is very tall and very deep might not be best suited for this purpose. The easier you can net your fish the less stress you will cause for them which is very important in this tank meant to heal your fish. You will also want to make sure you aren’t sharing the same water with your main system into the hospital tank. If your water is shared you could potentially infect the other fish in your system while trying to treat unhealthy fish. Since you will be using a separate water source for the tank, it is beneficial to have an easy way to change out the water as necessary. If you can set up your tank to easily drain out of the bottom it will save you time and effort.
MAINTAINING YOUR TANK
A few quick tips to keep your hospital tank running smoothly and effectively serving its purpose.
- Clean the tank after you have healed the fish you put into the tank. You do not want to have the disease linger in the tank afterwards.
- Make sure your tank is no frills, Don’t have lots of decor that you have to remove constantly to clean the tank, Only have the bare essentials for this tank as it is just a temporary holding spot to quickly heal your fish. Less parts means easier to clean,
- Keep your hospital tank up and running at all times. Being able to quickly transfer fish into the hospital tank at the first sign of trouble can save valuable time in minimizing spreading disease in your main system. You do not want to have to set up the tank after you have discovered disease and waste time allowing the infected fish to continue to infect the rest of your fish.
