Aqua One ReefSys 255

The Aqua One ReefSys 255 is a 90 cm rimless, open-top marine aquarium on a matching cabinet, with a glass sump underneath that you fit out with the equipment you choose. The display is low-iron Opti-Clear glass with a black glass back panel, and the sump, filter socks, plumbing and cabinet all come with it. 255 litres of water in the whole system.

Tank

• Tank 90 × 55 × 53 cm (L × D × H), 10 mm low-iron Opti-Clear glass, rimless and open-topped
• Black glass back panel to show off the colours of the reef
• Overflow box with a lid, which cuts algae growth in the overflow and keeps fish out of the plumbing
• Foam base supplied to sit under the tank

Sump

• Glass sump of 48 L in the cabinet, laid out so you can fit your own skimmer, heater and return pump
• Two baffles of adjustable height; one of them moves between three positions to suit the equipment
• Holder for two filter socks, both supplied, with low-splash sock silencers
• Separate chambers for the filter socks, a protein skimmer (steady water level), a refugium and the return pump
• Built-in 11 L top-up reservoir with its own lid, ready for an automatic top-up

Plumbing

• All plumbing supplied
• Main drain runs as a full siphon, tuned with a gate valve so it runs quietly
• Back-up emergency drain in case the main drain blocks
• Return line with a quick-connect coupling, so the return pump lifts out for cleaning
• Tested by Aqua One at flows of up to about 8,000 L/h through the sump

Cabinet

• Matching cabinet 90 × 55 × 80 cm (L × D × H) that keeps the sump and equipment out of sight
• Gloss black, gloss white or a concrete-look finish — choose the colour above
• Support leg and a foam base for the sump included

Specifications

Aqua One measures the sump and system volumes with the baffles at full height and about 3,500 L/h of flow; yours will vary a little with how the sump is set up.

What is not included

Return pump, protein skimmer, heater and lighting are not supplied, so you can choose your own. We can help you pick them to suit the tank.
