Bigger water volume is more forgiving — a mistake dilutes instead of spiking. ReefPicker lists 139 reef-ready systems from 15 brands, spanning 3.8–286 gal (14–1083 L). Most people starting out land between 16–34 gal (60–130 L): small enough to stock and light affordably, large enough that temperature and salinity hold steady between water changes.
Across the 139 systems listed here, display lengths run from 11.0" to 96.4". Length matters more than volume for two decisions: how many light fixtures span the tank, and whether a fixture's coverage reaches the corners. Every tank page on ReefPicker publishes its exact length, width and height, plus the internal chamber measurements where the manufacturer gives them.
An all-in-one (AIO) hides its filtration in a rear chamber built into the display — nothing to plumb, but equipment has to physically fit inside that chamber. A sump system drains to a separate tank in the cabinet, giving far more room for a skimmer and reactors. Of the 139 systems listed here, 44 are AIO and 94 are sump-ready. ReefPicker checks a skimmer or heater against the actual chamber measurements before it lets you add one.
Rarely by default — 8 of the 139 systems listed here ship with a lid, cover or mesh screen. It matters more than it sounds: many popular reef fish jump, and an open top is the most common way a healthy fish is lost. ReefPicker flags a jumper against the tank you picked, so the warning stays quiet when the tank is already sealed.
A working reef needs flow, light, heat, and something to export waste. For a typical 62 gal (234 L) system that means a return pump moving roughly 3–6× the display volume per hour, one or two wave makers, about 225 W of heating, and a skimmer rated at or above the display volume. ReefPicker sizes each of those against the tank you choose instead of a generic gallon bucket, and flags the parts that physically won't fit.
