Every soft-water shrimp keeper knows the problem: active soil substrate is essential for lowering the pH and stabilizing carbonate hardness. But after a few months or years, the buffering capacity of the substrate inevitably becomes exhausted. Until now, this meant that the entire aquarium had to be painstakingly emptied, the animals removed, and the tank completely redesigned. With the ShrimpPuddle Soil Background L, this enormous stress for you and your animals is finally a thing of the past!

Why the Soil Background L is a must-have for your tank:

• Effortless substrate replacement: The box is discreetly placed against the back wall of your aquarium and filled with active soil. Is the soil depleted after a while? Simply remove the box, empty it, fill it with fresh soil, and hang it back up – the rest of your hardscape and plant layout remains completely untouched.
• Consistently stable water parameters: By easily adding fresh soil to the background system, you keep the pH and carbonate hardness permanently within the ideal range without ever having to replace the deep-seated main substrate again.
• Excellent flow-through: The fine slots are manufactured with an exact spacing of 1.5 mm. They guarantee optimal, continuous flushing of the soil by the filter flow, allowing the water-influencing properties of the substrate to be fully utilized.
• Unobtrusive, slim design: The box is designed extremely flat and fits tightly against the aquarium glass. As soon as mosses, stem plants, or ferns grow in front of it, the system becomes almost invisible in the background of your aquascape.
• Optimized volume for nano & standard tanks: Size L offers sufficient capacity to reliably buffer the water parameters in aquariums with a volume of up to 60 liters.

⚠️ Important safety note for your animals:

To protect the sensitive biology and beneficial filter bacteria in your aquarium, please never replace the depleted soil 100% instantly. We strongly recommend emptying the box and refilling it with fresh soil gradually over several weeks. This prevents a sudden pH crash and gives your shrimp enough time to adapt to the changed water parameters.
