Want to own an aquarium that basically takes care of itself?

Generally speaking, regular fish tanks require you to change the water frequently, usually once every week or two.

Conventional aquariums also require you to clean the substrate every so often to keep your tank inhabitants healthy.

Changing the water or cleaning the substrate means you’ll have to repeatedly move fish from one tank to another.

Not only can this result in a high amount of stress on your fish, but it also means frequent human interference is needed, which isn’t always possible or reliable.

This is where a low maintenance fish tank comes in.

With a self-sustaining aquarium, you won’t have to change the water or clean the substrate as often. This will help establish a healthier environment for the fish as well as take some tedious tasks off your chore list.

A self-sustaining aquarium also creates a natural food chain so the fish tank can take care of itself with little outside help.

The Water Garden Self Cleaning Fish Tank from Back to the Roots is a small 3-gallon aquarium and an aquaponic tank 2-in-1 design.

The way it self-cleans is pretty smart; there’s a pump that circulates waste from the fish tank to the box of plants. The plants are then going to pick up the nitrogenous wastes so they work as fertilizer.

This operation keeps the water clean with minimal intervention on your part. However, the pump can be too powerful, so it’s not recommended for small fish as they may get sucked up.

The fish tank comes with several holes to house the cables of fish tank accessories, so you can customize your aquarium as you like.
