FAQs
How often should I clean the Nexus 220+?
Regular cleaning is essential. The frequency depends on the pond's stocking density and the amount of debris. Typically, cleaning every 1-4 weeks is sufficient.
What type of pump do I need?
The pump type will depend on whether you are pump-fed or gravity-fed. Consult the product manual for recommended flow rates and pump specifications.
What is the K1 Micro media?
K1 Micro is a type of media designed to provide a large surface area for beneficial bacteria, which convert harmful waste products into less harmful substances.
