Its 15 x 15 x 14-inch footprint fits beneath most aquarium stands in this size class, and the internal layout follows the same section-based organization as the larger IceCap 24 V2: a bubble-diffusing intake chamber, a built-in 4-inch filter sock holder, a skimmer section, and a return pump section — scaled to the space and flow demands of a nano to small reef.\u003c\/p\u003e\u003cp\u003eThe V2 revision of the SS15 introduced several changes: the freshwater reservoir was removed, the return pump section was expanded for more pump size and ATO routing flexibility, and two 1-inch intake drains plus an emergency drain holder were added. Built-in twin heater holders replaced the original suction cups. IceCap confirms exterior dimensions remain unchanged from V1, allowing upgrade without modifying stands or plumbing.\u003c\/p\u003e\u003cp\u003eThe 9.4 x 9.6-inch skimmer section is sized for nano and small reef protein skimmers. IceCap lists the K2 skimmer family — including the K2-50, K2-120, K2-160, and K2-200 — as recommended skimmer pairings for the SS15. The 4-inch filter sock holder is the same as the SS24 and fits the Klir Di-4 Auto Fleece Filter, though the Klir filter is sold separately.\u003c\/p\u003e\u003ch3\u003eKey Features:\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFor reef aquariums ranging from 10 to 80 gallons\u003c\/li\u003e\n\u003cli\u003eFootprint: 15 x 15 x 14 in (LxWxH)\u003c\/li\u003e\n\u003cli\u003eDurable acrylic construction\u003c\/li\u003e\n\u003cli\u003eBubble-diffusing intake chamber prevents microbubbles from reaching the return section\u003c\/li\u003e\n\u003cli\u003eDual 1-inch intake drains (V2 update)\u003c\/li\u003e\n\u003cli\u003eBuilt-in 4-inch filter sock holder with 200-micron sock prefilter included\u003c\/li\u003e\n\u003cli\u003ePerfect fit for Klir Di-4 Auto Fleece Filter (sold separately)\u003c\/li\u003e\n\u003cli\u003eSkimmer section: 9.4 x 9.6 in — sized for IceCap K2 series and other nano\/small reef skimmers\u003c\/li\u003e\n\u003cli\u003eReturn pump section: 4.7 x 9.4 in (expanded in V2)\u003c\/li\u003e\n\u003cli\u003eTwin heater holder — built in (V2 update)\u003c\/li\u003e\n\u003cli\u003eEmergency drain holder (1-in)\u003c\/li\u003e\n\u003cli\u003eTriple probe holder and four-slot tubing holder\u003c\/li\u003e\n\u003cli\u003eAdjustable water depth: 5 to 9 inches\u003c\/li\u003e\n\u003cli\u003eCompartment lids for quiet operation\u003c\/li\u003e\n\u003cli\u003eV2 change: freshwater reservoir removed; return pump section expanded; exterior dimensions unchanged from V1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat Changed in V2 vs V1:\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFreshwater reservoir: Removed\u003c\/li\u003e\n\u003cli\u003eReturn pump section: Expanded (additional space vs V1)\u003c\/li\u003e\n\u003cli\u003eHeater mounting: New built-in twin heater holder added\u003c\/li\u003e\n\u003cli\u003eDrains: New dual 1-inch intake drains + 1-inch emergency drain holder added\u003c\/li\u003e\n\u003cli\u003eExterior dimensions: Unchanged from V1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal For:\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNano and small reef hobbyists with aquariums in the 10 to 80-gallon range who want the organizational benefits of a dedicated external sump — probe holder, heater isolation, protein skimmer section — without the footprint of a larger sump\u003c\/li\u003e\n\u003cli\u003eHobbyists setting up their first reef system with a proper sump who want a purpose-built solution scaled to their tank rather than adapting a DIY or oversized sump beneath a small stand\u003c\/li\u003e\n\u003cli\u003eExisting IceCap 15 V1 owners who want to upgrade to the V2 improvements — expanded return section, built-in heater holders, new drains — without changing their cabinet or plumbing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePro Tips:\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatch your skimmer to the 9.4 x 9.6-inch skimmer section dimensions before purchasing.\u003c\/strong\u003e The SS15's skimmer compartment is meaningfully smaller than the SS24's 11.8 x 13.8-inch section.

The 24 x 14 x 16-inch footprint fits standard aquarium cabinets in this size class, and the internal layout divides the sump into clearly defined sections: a bubble-diffusing intake chamber, a filter sock compartment with a built-in 4-inch holder, a skimmer section measuring 11.8 x 13.8 inches, and a return pump section at 4.7 x 13.8 inches.\u003c\/p\u003e\n\u003cp\u003eThe IceCap 24 sump V2 improves on the original by removing the freshwater reservoir to save space and adding built-in heater holders for secure mounting.
