Product overview
The Aqua One ReefSys is an open-top rimless marine aquarium with low-iron Opti-Clear glass, a rear overflow, and a modular glass sump in the cabinet. You get the tank, weir, plumbing, and sump. Skimmer, return pump, wavemakers, and lights are chosen separately.
The sump has adjustable baffles, including a movable divider, so chamber size and water height can be set for a large skimmer or a refugium.
Key features
-
Opti-Clear glass: Unbraced low-iron panels so the viewing faces are not green-tinted.
-
Sump: Multi-chamber glass sump with two baffles (one movable).
-
Overflow: Main downpipe plus a higher emergency drain.
-
Socks: Dual filter-sock holders with silencer lids to cut splash.
-
Weir lid: Dark cover over the intake so light does not grow algae in the overflow.
-
Cabinet: Push-to-open doors with soft-close hinges.
Water and system compatibility
-
Water: Marine and reef only. Not for freshwater.
-
System: Display, cabinet, overflow, plumbing, and sump. Pair your own skimmer, return pump, and lighting.
