Every keeper of softwater shrimp knows the problem: active soil substrate is essential for lowering pH and stabilizing carbonate hardness. But after a few months or years, the buffering capacity of the substrate is inevitably exhausted. Previously, this meant that the entire aquarium had to be painstakingly emptied, animals evacuated, and the tank completely re-established. 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 Change: The box is discreetly placed against the back wall of your aquarium and filled with active soil. Is the soil used up after some time? Simply remove the box, empty it, fill it with fresh soil, and hang it back – your remaining hardscape and plant layout remain completely untouched.
• Consistently Stable Water Values: By easily introducing fresh soil into the background system, you maintain pH and carbonate hardness permanently in the ideal range, without ever having to replace the deep main substrate again.
• Excellent Flow: The fine slits are precisely manufactured with a 1.5 mm gap. They guarantee optimal, continuous circulation of the soil by the filter flow, so that the water-influencing properties of the substrate are fully utilized.
• Inconspicuous, Slim Design: The box is designed to be extremely flat and fits snugly against the aquarium glass. As soon as mosses, stem plants, or ferns grow in front of it, the system disappears almost invisibly into the background of your aquascape.
• Tailor-made for Nano Aquariums: In size M, the box offers the perfect dimension to reliably buffer water values in compact aquariums and nano cubes with a volume of up to 30 liters.

⚠️ Important Safety Notice for Your Animals:

To protect the sensitive biology and beneficial filter bacteria in your aquarium, please never replace 100% of the used soil abruptly. 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 adjust to the changing water parameters.
