Reef Octopus Regal 150SSS Skimmer Review: 600L Reef Build
When a Singapore reefer outgrows the Bubble Magus tier and starts looking for a skimmer that will run flawlessly for five years on an SPS-dominated tank, the conversation almost always lands on Reef Octopus. The Reef Octopus Regal 150SSS is the brand’s mid-large model designed for 500-700 litre mixed reefs and is one of the most-recommended units in the Singapore reefing community on Carousell forums. This review from Gensou Aquascaping at 5 Everton Park covers the 150SSS in detail — the Aquatrance pump, the space cone body, the SGD pricing tiers, and where it fits versus Bubble Magus and Aquaforest.
The Space Cone Design
The 150SSS uses Reef Octopus’s space cone body, where the cylindrical contact chamber transitions into a wider conical neck. This shape extends bubble dwell time before they reach the cup, which translates to denser, drier skimmate. The 150 designation refers to the contact chamber diameter (150mm); the SSS suffix marks the third revision with a refined Aquatrance 2000S pump. Body height is 670mm and total footprint is 320 x 240mm — plan sump space accordingly.
Pump and Power Draw
The Aquatrance 2000S is a needle-wheel AC pump rated at 1500 L/h air draw and 35 watts power. AC means no controllability — it runs at fixed speed — but reliability is exceptional. Reef Octopus claims a five-year mean time between failure, and field experience in Singapore reef builds backs that up. The trade-off versus DC competitors is no wet/dry tuning via pump speed; tuning happens entirely through water level adjustment and air valve control.
Singapore Retail Pricing
The 150SSS retails at SGD 880-1050 across local reef shops. Iwarna typically prices around SGD 950, Reef Discus Centre runs occasional sales near SGD 880, and Polyart stocks the unit at SGD 1020. Carousell parallel imports from US sellers run SGD 750-820 but lack warranty and arrive with US 110V pumps that need a step-down transformer for Singapore’s 230V grid — a SGD 80 hidden cost that erases most of the saving.
Tank Range and Bioload Reality
Reef Octopus rates the 150SSS for 500-700L heavily stocked or 800-1000L lightly stocked. In Singapore practice on a 600L mixed reef with 30 fish and an SPS-dominated rockscape, the unit pulls 80-120ml of dense skimmate per day. Drop the bioload to 15 fish on a softie-dominated 700L and output drops to 40-60ml — still healthy for the system. Undersize at your peril; oversize and you over-skim trace elements that corals need.
Tuning and Break-In
Allow three to four weeks of break-in. The 150SSS pulls dry and sometimes inconsistently for the first ten days, then settles. Target water height: 4cm below the neck transition. Air valve at fully open during break-in, then dial back 10 per cent if skimmate runs too wet. Pair the unit with a quality return pump running at 4-6x display volume per hour for proper sump turnover.
Sump Compatibility and Plumbing
The 150SSS needs a sump section at minimum 350 x 280mm and 600mm tall. Most off-the-shelf 4ft reef sumps from Eshopps or local fabricators accommodate it cleanly. Drain the skimmer cup to a waste container or auto top-off bucket; the cup holds roughly 2 litres before overflow. The cup gasket should be inspected quarterly — replacements cost SGD 25 from local reef shops or direct from Coral Vue.
Build Materials and Longevity
The body uses 10mm cast acrylic, joined with solvent welds rather than glued seams — a quality marker that separates Reef Octopus from budget brands. Internal silicone gaskets are EPDM, which resists ozone and saltwater for years. Realistic five-year cost of ownership including pump replacement at year four sits around SGD 1100. Compare with the protein skimmer category alternatives priced at SGD 600-900 that need pump and gasket service every two years.
Who Should Buy the 150SSS
Serious reefers running 500-700L mixed reef tanks with full SPS or LPS+SPS stocking, who value reliability over feature counts. Anyone planning to keep the same tank for five-plus years gets the best return. Skip the 150SSS if your tank is under 400L (use Bubble Magus Z5 instead) or if you need DC controllability for ozone or wet skimming experiments — look at the Reef Octopus Hydros line for that. For a workhorse skimmer on a flagship Singapore reef build, the 150SSS earns its premium.
