The mixed reef is reef-keeping's sweet spot: a community of soft corals, LPS, and the easier SPS in a single system. It rewards moderate care and forgives parameter drift better than dedicated SPS reefs.

Lighting

PAR 150–250 across the rockwork with shaded zones at substrate level for low-light corals like mushrooms.

Flow zoning

High flow at the top for SPS, gentle flow at the bottom for LPS, calm pockets for softies.

Coral placement order

Add softies first (zoas, mushrooms, leathers), then LPS (hammers, frogspawn, duncans), and only after 6 months add easy SPS (montipora, birdsnest).
