Genesis Rock Empty Power Rack — Biological Filter Holder, Rocks Sold Separately - Polyplab

Polyplab Genesis Rock Empty Power Rack — the holder alone for your Genesis Rock blocks

The Genesis Rock Power Rack is an organizer designed to hold up to four Genesis Rock blocks and add a huge amount of bacterial colonization surface without crowding your system. This version includes the rack and its flow deflectors — the ceramic rocks are sold separately.

What's in this version

• 1 Power Rack organizer (stackable)
• Water flow deflectors to fine-tune water movement
• Genesis Rock ceramic blocks sold separately

Why this holder

• Holds up to 4 Genesis Rock blocks (4 × 4 × ⅞ in each), each block offering over 1,000 m² (up to 11,000 sq ft) of bacterial surface.
• Compact footprint: tucks into a sump, an overflow box, or the filter section of an all-in-one.
• Aerobic or anaerobic, your choice: add or remove the flow deflectors to tune circulation.
• Stackable racks to add capacity in a small space.
• Simpler cleaning and maintenance, a tidier filtration area.

Who is it for?

Ideal if you already have Genesis Rock blocks, or if you'd rather build your system by buying the rack and the rocks separately.

Setup

• Insert your Genesis Rock blocks into the rack.
• Place the rack in a good-flow area of your sump, overflow, or filter section.
• Add or remove the deflectors depending on the type of bacteria you want (high flow = aerobic; low flow = anaerobic).
