ReefCrafter only publishes equipment pages when the product has real catalog data, images, vendor paths, and enough specs to support a useful fit check.
The tank sets every downstream constraint: water volume, floor load, light spread, flow pattern, equipment room, and livestock ceiling.
A reef light has to cover the tank footprint and hit the PAR band for the animals you actually plan to keep.
Skimmer gallons are marketing until they are scaled against the tank volume and bioload.
Display flow should be sized to the coral goal, not only the tank gallons.
A return pump should move enough water through filtration after head loss without turning the sump into a noisy washing machine.
The heater plan needs enough wattage to hold temperature without creating a dangerous stuck-on failure.
ATO is often a stability purchase before it is a convenience purchase, especially on small tanks.
A controller is useful when it reduces a real risk in the build, not when it replaces basic husbandry.
Water quality gear is not glamorous, but it decides how many algae and parameter problems you buy on day one.
Product pages are gated by active status, image availability, at least one reviewed outbound vendor URL, and category-specific spec readiness. If the page cannot say something useful about sizing or fit, it does not publish.
