We recommend refreshing your tank (cleaning it and adding fresh water) at least every 30 days to maintain consistent water chemistry. It's a simple process that only takes about 10 minutes.
If you add our plant-based water treatment solution, HydroBoost, to your tank weekly, you can also forgo our other recommended quarterly cleaning, which we call a Light Cleaning or sterilization of your device. Regularly adding HydroBoost to your Gardyn is the easiest way you can prevent and reduce unwanted algae, biofilm, nutrient, and salt deposits within your device so you can enjoy a cleaner Gardyn, healthier plants, and less frequent whole-device cleanings.
