Mantis Bio Sphere – 2kg

Description

Mantis Bio Sphere – 2kg — Bulk pH-neutral ceramic bio-media beads for sumps and multiple filters

A large sump or a fish room running several filters at once gets through bio-media quickly, and buying it in a bulk bag avoids topping up every few months from a small pouch. Mantis Bio Sphere – 2kg (SKU: MA069703) is the bulk bag of Mantis’s pH-neutral ceramic bio-media beads, built with an open flow structure and an ultra-high surface area for a large bacterial colony per kilogram of media. Being inert and pH-neutral, the ceramic adds no minerals or buffering of its own, so a sump can be topped up or re-seeded without shifting established water parameters. The 2 kg bag is sized to fill a full sump tray, split between two filters, or hold enough spare media to refresh an ageing canister without running short partway through.

The beads suit sumps, trickle filters, wet/dry towers, hang-on-back filters, or scattering directly in the tank, and the same bag is rated for freshwater, marine and pond systems. A microporous surface is what gives the beads their high specific surface area, where the biofilm of nitrifying bacteria actually forms rather than on the outer shell alone. Loose beads fill an oddly shaped sump compartment or a basket crowded with a pump or heater more completely than a solid block media, and because the 2 kg bag holds twice the volume of the 1 kg pack (SKU: MA069702), it suits a bigger single system or splitting between two chambers from one bag rather than buying two smaller ones.

Usage & Application

When to Use

• Large sumps: Filling a full-size sump tray or media chamber in one go.
• Multiple filters: Splitting one bag between two canisters, HOB filters or sump sections.
• Stocking up: Keeping spare media on hand to refresh a filter without a mid-batch top-up.
• Freshwater, marine or pond: One bulk bag suited to any of the three water types.

Placement & Usage Guide

• Rinse before loading: Rinse the beads under tap water to clear dust before filling the filter.
• Bag or basket it: Hold loose beads in a media bag or basket so they stay in the flow path.
• Split across chambers: Divide the 2 kg bag between two filters rather than overfilling one.
• Rinse, don’t replace, routinely: Clean gently in old tank water rather than swapping the whole batch at each service.
