If you have kept a fish tank before, one of the most basic questions is: how is a planted tank different?

All aquarium plants need 3 things for growth. Aquarium plants that don't get enough of each will deteriorate slowly over time.
The most important 'starting question' is whether we plan on growing shade plants or plants originating from open lakes. The light requirements for the former is quite different from that of the latter.
Many default kits (tanks + light + filter and/or other accessories) come with aquarium light that don't produce enough light to grow more demanding planted aquarium plants.
Read this detailed guide on choosing the right light in terms of strength and spectrum.
All plants need a set of elements to grow well. Many of these nutrients are available naturally in our tap water. Fish waste also provides some. However, many elements will be still missing if we don't add them.
Optimal fertilisation is one of the core pillars for great plant health. We can achieve this through aquarium plant substrate (for rooted plants) and through water column dosing. Consistency is the key.
Read this detailed guide on what nutrients plants need to grow and thrive.
Carbon dioxide levels in natural lakes are high (10-40+ppm) due to decomposition of organic material, that builds up CO2 gas, compared to equilibrium levels (2-3ppm) in a standard fish tank that has no CO2 injection.
Having optimal levels of CO2 in the tank is one of the biggest impact factors on plant health and quality of growth as 40% of plant dry mass is made out of carbon. This directly also affects algae presence/absence in a tank as algae presence has strong correlation to overall plant health.
Skipping CO2 injection still allows us to have nice planted tanks - if we pay special attention to choosing plants that can grow well in lower equilibrium levels of CO2.

Well, some hardy plants can survive in a tank designed primarily for fish. However we need a rather different set of tools to keep a larger variety of plants and to grow them in better form / aesthetics.
Some key adjustments are required ‘from the start’ and are difficult to implement to an existing fish tank, for instance adding a soil substrate.
Other adjustments such as upgrading lights or adding fertilisers can be done to existing tanks easily.
To start a successful planted tank without injected CO2, read the free guide below.
Although plants are the bottom of the food chain and seem plentiful in nature, they are actually harder to keep in good form than most common aquarium fish.
They require things like stronger lighting and for the planted enthusiast, carbon dioxide injection systems that can cost hundreds of dollars.
Are these additional items really necessary? It depends on the species of plants that you intend to keep.
Attractive plant species such as carpeting plants and red/orange plants all require CO2 to grow well. Some of them will survive in a non CO2 injected tank, but they grow with better health, density and coloration only with CO2 injection.
