Aquario Neo Soil is our top substrate recommendation for planted aquariums and is beautifully balanced for both beginners and experienced hobbyists growing advanced aquatic plants. Made from volcanic soil, Neo Soil buffers water to a slightly acidic pH, creating an environment ideal for fish health and aquatic plant growth. Its formula is optimized for lush plant growth, with several experiments showing the ability to grow carpeting aquarium plants like Hemianthus callitrichoides or Eleocharis ‘mini’ (hair grass varieties) in 60–90 days without additional fertilizers or additives.

This premium aquasoil contains specialized bacteria, activated by water contact, that help break down pollutants that can build up within substrates. Its double-layer structure makes it lighter than other substrates and creates surface area for beneficial bacteria to reproduce in bulk. Overall, Aquario Neo Soil offers many benefits to planted tanks from nano aquariums to large show tanks, and is suitable for all skill levels.

- When using this substrate, we recommend 30% water changes 1—3 times weekly after initial setup.

Below is our Ultum Nature Systems 45U 9 gallon tank using Aquario Neo Soil:

Aquario Neo Soil Planted Aquarium Tank Aquatic Plant Substrate

How much substrate do I need for my aquarium?
The general rule of thumb is one 3L bag for every 5 gallons of water. If you have a large aquarium, one 10L bag for every 20 gallons of water is a good starting point.

[Tank Length x Tank Depth x Desired Substrate Height (inches)] / 60 = Total liters of Controsoil required

Aquarium Substrate Comparison Guide

Sand, gravel, and aquarium plant soil can all be used to grow aquatic plants. But are they the same? The short answer is no. Here’s our take on each substrate type.

3 different freshwater aquarium substrates used in a 9 gallon nature-style aquascape

Natural Cosmetic Sand

Aquarium sands are suggested for cosmetic purposes only and are usually paired with aqua soil when creating a nature-style aquarium. In some cases, hobbyists might choose natural sand as a main substrate and add nutrients back in via aquatic plant root tabs. This is enough to feed some low-tech aquarium plants. However, it isn’t sustainable long term since they dissolve and deplete quicker than plant soil. If you want a full sand look, try adding a base layer of soil first then topping it with your preferred sand. This way, you don’t miss out on the added benefits of aquarium soil and your aquatic plants get the nutrients they need. Overall, natural sand is an aquascaping staple. It’s available in many colors and also provides enrichment for bottom-dwellers who enjoy sifting through!

Optional hot tip: Use a sand flattener or brush to create a 0.5-1” gap between your soil layer and the tank panels. Then, pour your sand on top for extra clean edges. No soil peeking through here!

Aquarium Gravel

Like sand, gravel is another aquascaper’s choice. We’ve heard them used interchangeably, but they’re not the same! Gravel is a chunkier medium and can be used independently or as detail accents on top of a fine-grain sand base. Depending on your tank size, gravel may be a better option as it covers more surface area as well. Personally, we really enjoy using gravel as an accent in our aquascapes as sometimes sand alone can look too plain. A sprinkle of gravel here and there really adds that extra bit of fine detail that can elevate the entire look of a nature-inspired aquascape. Here are some of our previous tanks with gravel being used as an accent vs. a gravel-only planted tank.

Aquatic Plant Soil

The term aqua soil generally encompasses any substrate that contains nutrients and is designed specifically for tropical freshwater aquarium use. These aquarium plant soils usually contain micro and macronutrients or may offer features like dormant beneficial bacteria and water buffering capabilities. This is why rinsing prior to use isn’t recommended! Doing this washes away some of the good stuff that plants love. Popular aquarium plant types like Echinodorus, Cryptocoryne, various stem plants and Vallisneria species reap the best benefits from aquatic plant soil. Using them also supports the proper cycling of a new tank.

You’ll notice higher quality soils usually contain natural ingredients like volcanic ash and clay, which are then high pressure baked into granules. The spherical shape prevents your soil from turning into mud over time and can be useful when creating slope hills in your aquascape. Some aquarium substrates like Ultum Nature Systems Controsoil, come in two different colors and three granule sizes. The soil’s ingredients are the same, but choosing the correct granule size is important and can be game changing. Carpeting aquarium plants like Glossostigma elatinoides, Hemianthus callitrichoides ‘Cuba’, Micranthemum ‘Monte Carlo’, and Eleocharis (dwarf hairgrass) varieties are much easier to plant in extra-fine substrate types. The smaller granule also makes it easier for the plant’s roots to take hold and become established. On the flip side, large root aquarium plants like amazon swords (Echinodorus sp.) and jungle vals (Vallisneria sp.) will be easier to plant and root in larger soil granules.

Using aquarium soil, sand, and gravel while sloping it towards the back of the aquarium without mixing

There you have it! One important thing to note is that aquarium soils don’t last forever. In general planted tank conditions, most quality soils will last between 8-12 months before depletion. When you reach this point, here are some of the common options:

Revitalize the soil with aquarium plant root tabs!
Keep the same scape, remove some plants, top off with a fresh soil layer and replant.
Use this as an opportunity to do a full rescape.
