An aquaponics fish tank is so cool! If you don’t know what they are before reading this post, you’re definitely going to want one by the time you finish reading.
Aquaponic fish tanks (sometimes known as Eco Fish Tanks or Hydroponic Fish Tanks) are special tanks with plants on top. The fish waste can be made to fertilize and support the growth of healthy plants, while the plants are cleaning the tank. They could be considered more low maintenance fish tanks.
Let’s find out more about these great products, and who knows? Maybe by the end of it you’ll be buying your very own hydroponic fish tank.
Fish Tank Aquaponics & Hydroponics
Why is an aquaponics fish tank so great? Here are a few of my favorite things about them:
The plants clean the fish tank
The fish waste is turned into fertilizer for the plants
Plants aerate the water for the fish
Microgreens can be ready to harvest from an aquaponics fish tank, like those listed below, within 10 days. Herbs and other plants will take longer to be ready for harvest, but half the fun is in watching this fish tank with plants on top!
1. Back to the Roots Water Garden Betta Fish Tank Starter Kit
This Back to the Roots Aquaponics Starter Kit is indeed a great way to get started in fish tank aquaponics. Back to the Roots was started by a couple of guys just out of college, who have a passion to reconnect families with food through indoor gardening kits.
This tank is made for Betta fish (aka Siamese fighting fish) but can be used for other small fish as well. The general rule is 1 gallon of water for 1 inch of fish. In this 3 gallon tank you could have up to 3 very small fish (like male guppies) or 1 slightly larger fish (such as a Betta).
You can grow a range of plants from the top of this tank. The kit comes with plenty of wheat grass and radish sprouts to get you started. These plants are good starter plants – they grow quickly and easily, and don’t need a lot of light.
2. Penn-Plax Aquaponic Betta Fish Tank Promotes Healthy Environment for Plants and Fish
This Penn-Plax eco fish tank is a smaller option than the one listed above. It can be bought in either a 0.5 gallon size, or 1.4 gallons. I would recommend getting the larger size as this will be best for your fish. 0.5 gallons is a very small amount of water and even a very small fish may quickly outgrow this tank.
Seeds are not recommended for use with this aquaponics fish tank, you will need to purchase a houseplant with good roots. Recommended plants include bamboo, Chinese evergreen, lettuce and peace lilies. In the resource section at the bottom of this page you will find a link to some more of the best plants for aquaponic fish tanks.
The water in this tank will need to be changed and treated every so often. If you live in a cool climate, a Betta will need to be transferred to a heated tank during the colder months. The best temperature for Betta fish is between 75 and 80 degrees Fahrenheit. This fish tank looks great even without fish in it, it is still a very unique set-up as it’s not everyday you get to see a plant’s roots like this (unless you have this tank of course!).
The AquaSprouts Garden eco fish tank is next up on the list. This is a much larger set-up than the two listed above, having the capacity to hold a 10 gallon tank. Check out the following promo video for the AquaSprouts Garden.
It is important to realize that the kit does not come with a tank or grow-lights – these must be purchased separately. Here are the products that are most commonly bought with the AquaSprouts Garden:
The Marina 10 gallon Aquarium Kit is a quality glass aquarium that fits the AquaSprouts Garden. It has been very well reviewed and comes with everything you need to get started with happy healthy fish. This includes LED lighting, fish food, water conditioner, supplements, a fish net, filter and care guide. It’s a great value.
Hydroplanet’s 2 foot fluorescent bulbs for indoor gardening fits the Aquasprouts Garden light bar. Any 2 foot lighting will fit and be compatible with the aquaponic set-up. Hydroplanet’s lights are a quality product and have been highly rated.
Those three are top picks for a hydroponic fish tank. But here are a couple other slightly different tanks that you might like to check out.
The Sweetsea wall mounted tank is a small and cheap aquaponic fish tank. It holds very little water, having two size options: 0.5 gallons or 1 gallon. It is only suitable for 1 small fish, and the larger tank is the best choice. This is a really unique fish tank that will wow your visitors and make them go ‘by golly’, though it is not for growing food.
Another special option is the Penn-Plax AquaTerrium Planting Tank. Like the one above, this one is also not for growing food. It comes in 3 sizes; small, medium and large. It is an open tank with the plants growing at the back and it has its very own waterfall!
