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

Why the Soil Background M 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 substrate. Is the substrate exhausted 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 substrate to the background system, you keep the pH and carbonate hardness permanently in 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 substrate by the filter flow, so that the water-influencing properties of the substrate can 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 almost invisibly disappears into the background of your aquascape.
• Tailor-made for nano aquariums: In size M, the box offers the perfect dimensions to reliably buffer the water parameters in compact aquariums and nano cubes with a volume of up to 30 liters.

⚠️ Important safety note for your animals:

To protect the sensitive biology and beneficial filter bacteria in your aquarium, please never replace the exhausted substrate 100% instantly. We strongly recommend emptying the box and then refilling it step by step with fresh substrate over several weeks. This prevents a sudden pH drop and gives your shrimp enough time to adapt to the changing water parameters.
