NEPTUNIAN M - PRO 90 white
Neptunian Cube M-Pro 90
The Neptunian Cube M-Pro 90 gives you significantly more display and filtration space while retaining the clean, minimalist appearance that makes the M-Pro range stand out.
The 90cm display uses 12mm Opti-White glass and Neptunian’s ultra-slim weir system, with the plumbing kept out of sight for an uncluttered aquascape. Underneath, the large multi-chamber sump provides dedicated space for filtration equipment while still incorporating an RO top-up reservoir and electronic dry storage area.
