Every owner of softwater shrimp knows the problem: active soil substrate is essential for lowering the pH value and stabilizing carbonate hardness. But after a few months or years, the buffering capacities of the substrate are inevitably exhausted. Until now, this meant: the entire aquarium had to be painstakingly emptied, animals evacuated, and the tank completely re-setup. With the ShrimpPuddle Soil Background XL, this enormous stress for you and your animals is finally a thing of the past!

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

• Effortless Substrate Change: The box is discreetly placed at the back of your aquarium and filled with active soil. Is the soil exhausted after some time? Simply take out the box, empty it, refill with fresh soil, and hang it back – your remaining hardscape and plant layout remain completely untouched.
• Permanently Constant Water Values: By easily introducing fresh soil into the background system, you keep the pH and conductivity permanently in the ideal range, without ever having to replace the deep-seated main substrate again.
• Excellent Flow: The fine slots are manufactured with an exact spacing of 1.5 mm. They guarantee optimal, continuous circulation of the soil by the filter flow, so that the water-influencing properties of the substrate come fully into play.
• Unobtrusive, Slim Design: The box is designed to be extremely flat and fits snugly against the aquarium pane. As soon as mosses, stem plants, or ferns grow in front of it, the system almost invisibly disappears into the background of your aquascape.
• Large Volume for Medium Aquariums: In the XL version, the box offers sufficient capacity to reliably buffer the water values in aquariums with a volume of up to 100 liters.

⚠️ Important safety notice for your animals:

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