Updated How we research
ADA Aqua Soil Amazonia Ver 2 (9L)

Aqua soil is a nutrient-rich, granular substrate baked from natural soils, designed to feed plant roots while gently softening and acidifying the water. Many demanding species, especially carpeting plants and vivid stems, root faster and grow denser in an active soil than in inert gravel. Look for a grain size that suits your plants, since finer grains help delicate carpets while larger ones improve flow through the bed. Note that most aqua soils release ammonia early on, so a proper cycle before adding livestock is important. This substrate suits aquascapers aiming for a lush, high-detail planted layout and anyone keeping soft-water species that appreciate a lower pH. Beginners drawn to iwagumi or nature-style scapes will find soil forgiving for plant health, though it does break down over a few years and eventually needs refreshing. If your goal is fast establishment and rich growth rather than a purely decorative bottom, aqua soil is the classic choice.
