Setting up your first planted tank

The short version: a successful first planted tank comes down to four things, in order of importance: a nutrient-rich or capped substrate, enough of the right light, a few genuinely easy plants, and a simple fertiliser routine. Get those right and you can skip pressurised CO2 to start. Plant heavily from day one, choose low-demand species, keep the light on a timer for six to eight hours, and be patient through the first few weeks while the plants settle in and the tank finds its balance.

Step 1: Substrate

Plants root in and feed through the substrate, so this is where to spend your effort. You have two common paths: an active planted soil that feeds the roots directly, or plain gravel or sand with root tabs added for heavier feeders. Have a look at the gravel and substrate options and pick one made for planted tanks if you want the easiest start.

Step 2: Light

Plants need a light built for growth, not just for viewing. A dedicated plant LED like the Fluval Plant Spectrum LED gives you the intensity and spectrum plants use. Run it on a timer and start at a moderate level, since too much light too soon feeds algae before your plants can outcompete it. See the full range in lighting and canopies.

Step 3: Choose easy plants

Beginner success is mostly about plant choice. Start with hardy, low-light species such as anubias, java fern, cryptocoryne and vallisneria, which forgive mistakes while you learn. Our live plants collection lists what grows well for local aquarists. Plant densely at the start; a heavily planted tank resists algae far better than a sparse one.

Step 4: Feed the plants

Plants need nutrients as well as light. A liquid fertiliser and, for root feeders, root tabs cover most of what an easy setup needs. Browse plant fertiliser and additives. If you want to push growth without a full CO2 system, a liquid carbon supplement is a middle step, and we cover pressurised CO2 in a separate guide below.

The first month

New plants often drop leaves as they convert to underwater growth, then push out new ones adapted to your tank. This is normal. Keep up your water changes, resist the urge to crank the light, and let the tank settle. Test your water while things stabilise so you can catch an ammonia or nitrite spike early.
