Product Overview The Dymax eZ Filter is a high-performance internal aquarium filter system engineered to deliver complete 3-stage filtration for both freshwater and marine environments. Powered by a heavy-duty Dymax pump, it houses organized filter media baskets for easy maintenance and supports modular upgrades, including direct attachment of the Dymax IQ Skimmer for saltwater reef setups. Key Features & Benefits Complete 3-Stage Filtration Basket: Features modular compartments loaded with white wool (mechanical), activated carbon (chemical), and a biological sponge (biological) for crystal-clear water. Dual-Level Intake Draw: Pulls water concurrently from both the upper surface and lower depths of the tank to clear floating debris and settled detritus. Freshwater & Marine Compatible: Versatile internal design works seamlessly in planted freshwater displays, nano aquascapes, and marine saltwater setups. Attachable Skimmer Upgrade: Integrates directly with the Dymax IQ Skimmer (sold separately) to combine protein skimming and biological filtration into a single compact unit. High Surface Area Biological Housing: Porous sponge and media baskets foster massive colonies of beneficial nitrifying bacteria to cycle ammonia and nitrites. Easy-Access Maintenance: Removable internal media basket allows for quick, mess-free filter pad cleaning and replacement. Technical Specifications Always rinse filter media in drained aquarium water to protect established nitrifying bacteria colonies.

What size aquarium is the Dymax eZ Filter best suited for?The Dymax eZ Filter line is designed for tanks ranging from 60cm to 90cm in length and around 30cm in height, covering aquarium volumes from 27 gallons up to 53 gallons depending on the selected model (EF-20, EF-30, or EF-40). 2. Can I use the Dymax eZ Filter in a saltwater marine aquarium?Yes! The eZ Filter is fully marine safe. For reef and saltwater setups, you can attach the Dymax IQ Skimmer directly to the unit so protein skimming and multi-stage filtration are handled by one consolidated internal system. 3. How should I clean the included filter media during routine maintenance?Always rinse the biological sponge and filter basket in a bucket of drained aquarium water. Avoid tap water, as chlorine will destroy the beneficial nitrifying bacteria living inside the media.
