The Smart Pond Dosing System Controller Add-On Kit, when paired with the Smart Pond Dosing System XT, enables the simultaneous addition of two water treatments to your pond, waterfall, or fountain. This kit simplifies the application of a second 64 oz. treatment, enhancing your water treatment routine. Maintain for Ponds serves as the essential treatment for ponds, while Prevent for Fountains is ideal for fountains and waterfalls. Combining these foundational treatments with our specialized solutions can yield remarkable results. For instance, using Maintain for Ponds alongside Clear for Ponds can significantly improve water clarity. Each controller connects to the Aquascape Smart Control App, allowing for easy dosage adjustments and low treatment alerts directly on your smartphone or tablet. The kit includes one control panel, one treatment intake assembly with a low treatment alert, and all necessary tubing and cables.
