Do you have different substrate layers to benefit the most for planted tank setups?

Layering substrate can definitely boost plant growth, but it's not strictly necessary for all tanks. A common method is to use a nutrient-rich base layer, like aqua soil or even capped garden soil, and then cover it with an inert substrate like sand or gravel. The idea is to give roots easy access to nutrients, while the top layer prevents clouding and keeps the nutrients from leaching into the water column too quickly.

For example, some people use about an inch of organic soil or specialized plant substrate at the bottom, capped with 1-2 inches of sand or fine gravel. Others stick to just one type, like ADA Aqua Soil, especially if they don't want to mess with layering.

If you grow heavy root feeders (like swords or crypts), the base layer really helps. For low-tech setups or plants that feed more from the water (like Java fern or Anubias), a single inert layer is fine, and you can supplement with root tabs.

Layering can mean better long-term nutrient supply, but it also adds complexity when rescaping or planting new things. So, it's a balance—use it if you want to maximize growth, especially with demanding plants, or keep it simple if you value easy maintenance.
