Oase ScaperLine soil is an outstanding choice for planted aquascapes - the active substrate lowers the hardness of the water, looks stunning and promotes terrific plant growth. It creates a slightly acidic pH range that is beneficial for most aquarium plants as it makes it easier for them to take in nutrients. The active soil also absorbs nutrients from the water and releases them again when required - this buffer effect is ideal for long-lasting, healthy plant growth. The grain size of our ScaperLine soil is suitable for small to large scapes and lets plant roots develop a firm hold. The soil grains are baked at lower temperatures and are agreeably robust but not too dense. The soil resists compaction to let roots grow freely through it in your aquascape.
