If you’re looking to level up in your aquarium keeping skills, consider adding live aquatic plants. Not only do they add a natural beauty to your tank, but they also help consume toxic waste chemicals and purify the water for your fish. Follow along as we step you through the process of setting up your first low tech planted aquarium.
Let’s first form a shopping list of necessary materials. If you are new to planted aquariums or are working on a limited budget, there’s no need to get a rimless, low-iron glass aquarium that costs a fortune. A regular glass tank from your local pet store works just fine, and the rim actually serves a purpose to help buffer against any unevenness between the aquarium and the stand.
The fish tank should be placed on a hard and level surface, such as an aquarium stand, kitchen counter, or solid piece of furniture. Make sure that the surface (and the floor beneath it) can support the weight of the entire aquarium setup, which may weigh nearly 10 pounds per gallon once you add the water, substrate, equipment, and decorations.
While an aquarium lid may seem like an unnecessary expense, we highly recommend getting one because it minimizes heat loss and the amount of electricity the heater uses. A lid also decreases evaporation, which can cool the tank and cause swinging water parameters that stress your fish. Plus, a fish tank cover is a simple way to prevent fish, shrimp, and snails from accidentally jumping or climbing out of the aquarium.
An aquarium lid stops fish from jumping out and other household pets from getting in.
An aquarium background is optional but nice to have since it hides the power cables and airline tubing from view. You can buy a background from the local pet store, spray the back panel of the tank with Plasti Dip rubber coating, or even tape posterboard to the aquarium. We personally like black backgrounds since the color seems to make plants stand out more and hides algae better.
A heater and thermometer are usually necessary if you plan to keep tropical fish. Read our full article on how to choose an appropriately sized heater for your setup.
For lighting, there are many, many options to choose from, so in general, we recommend that beginners go with a planted LED light because they are designed to provide the optimal spectrums and PAR (Photosynthetically Active Radiation) levels for growing aquarium plants. The Finnex Stingray light is our personal favorite because of its solid performance and great value for low to medium light plants, but for more choices, read our article on how to pick the best planted aquarium light for your specific needs. A light timer is also extremely helpful for making sure your plants get a consistent amount of light every day and preventing algae growth.
Substrate is another hotly contested topic in the planted aquarium world. Dirt and enriched soils are often touted as the best options because of their high amounts of nutrients, but these excess nutrients can leak into the water and cause water quality issues or algae blooms for inexperienced hobbyists. Therefore, we recommend that beginners start with inert substrates that contain no nutrients, such as aquarium gravel or coarse sand. For more information, find out how to pick the best substrate for your planted tank.
Tweezers are useful for planting aquarium plants or adding root tabs into the substrate.
You can design your aquarium using only live plants, but many people like to add hardscape, such as aquascaping rocks and driftwood that are safe for fish tanks. You can look online for inspiration or pick whatever looks good to you. Other useful planted tank supplies include:
Finally, let’s talk about buying the live aquarium plants. The reason why we saved them for the very end of the checklist is because you should wait until you have almost everything set up before shopping for them. For example, it would be unfortunate if you got your new plants and then realized that you don’t have enough substrate to cover 2-3 inches of the tank bottom. Here are some helpful tips when making your plant selection:
Now that you have all the supplies ready, here is a step-by-step guide to assembling your aquarium:
Choose a location for your aquarium in a low traffic area out of direct sunlight that has nearby access to an electrical outlet and running water.
Before you add any water, spend time moving around the hardscape and plotting out where the plants will go.
Don’t feel like you have to copy the professional aquascapes you see online. Use your creativity and design your planted aquarium in a way that is most pleasing to you.
If some of your plants' leaves start melting, do not throw away the plants. Most likely they are growing new, smaller leaves that will be more accustomed to living underwater in your local tap water, as described in this article. However, if your plants are still not doing well three to four weeks after planting them, read our article on plant nutrient deficiencies to make sure they’re getting all the essential building blocks they need.
