The Aqua One 137s blue sponge pad is a genuine replacement coarse filter sponge designed exclusively for the Aqua One Ocellaris 850 and 850-UVC external canister filters. It serves as a vital multi-stage media component to keep your aquarium clean and stable.
Key Functions
- Mechanical Filtration: It features a coarse, 15 PPI (pores per inch) profile designed to trap larger solid waste and organic debris. This prevents finer polishing pads (such as the 137w or 138s) from clogging prematurely.
- Biological Filtration: The porous structure provides an ideal surface area for beneficial aerobic bacteria cultures to thrive, which break down harmful ammonia and nitrites.
Product Specifications & Features
- Compatibility: Made specifically for the Aqua One Ocellaris 850 and 850-UVC canister filters.
- Pack Size: Typically sold as a 2-pack (providing up to a year's supply depending on bioload).
- Material: Coarse blue sponge foam.
- Maintenance: Low maintenance and easy to install directly into the designated media baskets.
Maintenance & Replacement Schedule
- Routine Cleaning: During regular filter maintenance (approx. every 4 to 6 weeks), rinse the sponge thoroughly in a container of water taken from your aquarium. Never use tap water, as the chlorine will kill the beneficial biological bacteria.
- Replacement: Manufacturers and retail specialists suggest replacing the sponge entirely every 4 to 6 months (or 16 weeks). Over time, older sponges lose their structural shape, begin letting too much debris pass through, and cause a noticeable reduction in the filter's water flow rate.
