A step-by-step guide to using Dennerle Scaper's Soil 8L: how deep to lay it, how to plant without clouding the water, and how to cycle a new aquasoil tank safely.
Quick answer
Use Dennerle Scaper's Soil 8L as the main substrate layer at roughly 4–6 cm deep, plant it damp before filling, and cycle the tank for 4–6 weeks with frequent water changes and a test kit before adding shrimp or fish.
Why Scaper's Soil changes your planting and cycling routine
Dennerle Scaper's Soil is a nutrient-rich granule substrate, not an inert gravel. That means it releases minerals slowly over time, which supports root development and colour but also means a new tank can run hot with nutrients in the first weeks. Your planting technique and water-change schedule need to account for that.
The 8L bag suits a small-to-mid aquascape. For a standard 60 cm tank you will likely need more than one bag to reach a proper depth, so plan the layout before you open it. If you are unsure whether soil is right for your setup, compare it with inert options first; this guide assumes you have already chosen an active soil.
When to plant damp instead of flooded
Planting in aquascape soil is easiest when the substrate is damp but not submerged. Dry granules shift under tweezers, and a flooded tank makes it harder to see root placement. Damp soil holds its shape, so stems and rosettes stay where you put them.
The exception is very fine carpet plants: if they keep floating, flood to just above the substrate line, plant, then drain back down before the main fill. This is slower but saves repeated replanting.
Step-by-step: setting up, planting, and cycling with Scaper's Soil
- Lay the substrate to depth: Add Dennerle Scaper's Soil 8L in a layer about 4–6 cm deep at the front and up to 8 cm at the back for a sloped aquascape. One 8L bag covers a small nano tank; for a 60 cm tank, buy two bags so you do not run short mid-layout. Check depth with a ruler before you plant; too shallow and stems uproot, too deep and you waste soil.
- Plant while the soil is damp: Mist the soil until it is damp but not pooling, then plant with tweezers at a shallow angle. Push stems in to the first leaf node and firm the soil around the base. Work from the back of the tank forward so you do not kneel on planted areas. If a plant floats within an hour, replant it immediately rather than waiting for the fill.
- Fill gently to avoid clouding: Place a plastic bag or plate over the substrate and pour water onto it slowly. Fill to about half, check the layout, then finish. Expect some cloudiness from the granules; it usually settles within 24–48 hours with the filter running. Do not rinse the soil before use; rinsing washes out the nutrients that make it active.
- Start the cycle with heavy water changes: Run the filter and heater, and change 50% of the water every two to three days for the first two weeks. This removes excess nutrients released by new aquasoil and protects plants from algae blooms. Test ammonia and nitrite every few days. If ammonia stays above 0.5 ppm after two weeks, increase water-change frequency rather than adding livestock.
- Wait for a stable cycle before adding shrimp: Do not add shrimp or fish until ammonia and nitrite read zero on two consecutive tests, usually 4–6 weeks. Add a small cleanup crew first, then wait a week before adding fish. Keep testing through the first month. Shrimp are more sensitive to lingering ammonia than fish; give the tank an extra week if you are unsure.
Product facts
- Dennerle Scaper's Soil 8L: Dennerle Scaper's Soil is a nutrient-rich granule substrate that releases essential minerals slowly over time. That slow release feeds roots and colour, but it also means you should not add extra root tabs in the first weeks.
