Frequently Asked Questions
1. Can the Dymax PowerHead be used in a marine saltwater reef tank? Yes! The Dymax PowerHead features a durable roto-magnetic drive mechanism designed to resist corrosion, making it fully compatible with saltwater marine and reef setups as well as freshwater aquariums.
2. Can I run the Dymax PowerHead inline outside of the water? No, the Dymax PowerHead is a fully submersible water pump that relies on surrounding aquarium water for cooling and lubrication. Operating the pump dry will overheat the motor and damage the magnetic rotor shaft.
3. How do I perform routine maintenance on my powerhead pump? Unplug the unit, remove the front intake housing, and pull out the magnetic rotor assembly. Rinse away trapped biofilm, algae, or mineral deposits using warm water or a mild vinegar soak every 2 to 3 months to maintain maximum flow efficiency.
