Reef Lighting & Automation Kit

Coral color and growth depend on the spectrum (blue light drives photosynthesis and pops the fluorescent colors) and intensity (too little and they brown, too much and they bleach). A programmable LED ramps the light up and down on a schedule that mimics a natural reef day — dawn, midday, dusk.

Adding the elements the corals consume — calcium, alkalinity, magnesium — in measured daily amounts as the corals pull them out of the water. A dosing pump and a test kit (or a controller that tests automatically) keep the levels rock-steady, which is what corals need to build their skeletons.

Water evaporates from a reef tank (but the salt stays), so the salinity rises steadily without top-off — stressful for coral. An auto-top-off replaces the evaporated water with fresh RO/DI, automatically, keeping the salinity locked. It is the single biggest stability upgrade for a reef.

Daily-ish while the tank matures, weekly once stable — alkalinity, calcium, nitrate, phosphate. The test kit (or a controller) is the dashboard; the numbers tell you what to dose. A reef is managed by data, not by guess. Test, log, dose — repeat.
