When you're shopping for your first aquarium, you're often asked: "Do you want a plant substrate?" To which I often think, "Is that really necessary?" We've researched it for you and gathered all the answers in this blog post about substrate and aquariums!
An aquarium without plants is possible. The most important factor is the conversion of ammonium and nitrate. This can be achieved with an aquarium filter and/or aquarium plants. However, make sure there are plenty of hiding places and good filtration if you choose not to have plants.
Aquarium plants can make your aquarium shine or make it look like a battlefield. Fortunately, plants don't have to be so difficult to care for. With less lighting, plants grow more slowly and generally do better... at least, if you have the right aquarium plants.
It's always recommended to have at least one plant per 10 liters. However, you can also choose more or fewer plants. If you choose more plants, also provide more nutrients and CO2.
If you keep this equal to the quantity demanded by the plants, you can in principle add an unlimited amount of plants.
Adding CO2 isn't always necessary! There are other tricks you can use without buying an expensive CO2 system. Here are four tips for increasing CO2 levels in your aquarium and reducing your aquarium plants' CO2 needs without the use of a fancy CO2 system.
Real aquarium plants are good for the aquarium's metabolism; they break down waste products, nitrates, and phosphates. They also oxygenate the aquarium water. Fast-growing plants can also have an anti-algae effect.
