{"product_id":"red-coral-macroalgae","title":"Red Coral Macroalgae","description":"\u003ch2\u003eRed Coral Macroalgae\u003c\/h2\u003e\n\n\u003cp\u003eRed Coral Macroalgae (\u003cem\u003ePeyssonnelia novae-hollandiae\u003c\/em\u003e, provisionally) is one of the most extraordinary and visually deceptive specimens in the reef hobby — an Australian macroalgae that grows into a \u003cstrong\u003ehard, sculptural, upright branching structure of deep crimson red\u003c\/strong\u003e that is virtually indistinguishable from living precious coral at first glance. Visitors to your tank will do a double take every time. What appears to be an elegant colony of rare red coral is in fact a macroalgae — photosynthetic, functional, and quietly working to export nitrates and phosphates while serving as a haven for copepods and microfauna throughout its complex branching architecture.\u003c\/p\u003e\n\n\u003cp\u003eWhat makes Red Coral Macroalgae genuinely unlike anything else in the hobby is its physical structure. The thallus is hard and cartilaginous — firm to the touch, permanently holding its coral-like branching form regardless of flow or current. It does not wilt. It does not melt. It does not collapse under strong flow or go limp in low-nutrient systems the way softer macroalgae can. Place it in your aquascape and it stays exactly as positioned — a permanent, living crimson sculpture that grows slowly and organically over time into an increasingly impressive colony.\u003c\/p\u003e\n\n\u003cp\u003eSourced from Australian waters and essentially unknown in the reef hobby worldwide, Red Coral Macroalgae is a genuine first — a species that has never been commercially available before, and that delivers on every level a serious reef keeper could ask for. It is functional, structurally unique, visually stunning, and completely unlike anything else on the market.\u003c\/p\u003e\n\n\u003chr style=\"border: 0; border-top: 1px solid #dde5e8; margin: 18px 0;\"\u003e\n\n\u003ch3 style=\"color:#1a5a61;\"\u003eAvailable Options\u003c\/h3\u003e\n\n\u003cdiv style=\"background: linear-gradient(180deg,#f6fbf8 0%, #edf7f2 100%); border: 1px solid #d4e6e3; border-radius: 12px; padding: 13px 15px;\"\u003e\n  \u003cp style=\"color:#1a5a61; margin-bottom:6px;\"\u003e\u003cstrong\u003eStarter Plant\u003c\/strong\u003e\u003c\/p\u003e\n  \u003cul\u003e\n    \u003cli\u003eOne healthy Red Coral Macroalgae specimen (\u003cem\u003ePeyssonnelia novae-hollandiae\u003c\/em\u003e, provisionally) with established branching structure\u003c\/li\u003e\n    \u003cli\u003eHard, cartilaginous form — arrives holding its shape and ready to place as an immediate display piece\u003c\/li\u003e\n    \u003cli\u003eA rare opportunity to own a species that has never been commercially available in the hobby before\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003chr style=\"border: 0; border-top: 1px solid #dde5e8; margin: 18px 0;\"\u003e\n\n\u003ch3 style=\"color:#184f69;\"\u003eCare Information\u003c\/h3\u003e\n\n\u003ctable style=\"width:100%; border-collapse:separate; border-spacing:10px 10px;\"\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"width:50%; background:#eceff1; border:1px solid #cfd6da; border-radius:10px; padding:11px 13px; color:#22323a; vertical-align:top;\"\u003e💡 \u003cstrong style=\"color:#435760;\"\u003eLighting\u003c\/strong\u003e\u003cbr\u003eLow to Moderate — deep red coloration maintained best under moderate spectrum\u003c\/td\u003e\n    \u003ctd style=\"width:50%; background:#eceff1; border:1px solid #cfd6da; border-radius:10px; padding:11px 13px; color:#22323a; vertical-align:top;\"\u003e🌊 \u003cstrong style=\"color:#435760;\"\u003eWater Flow\u003c\/strong\u003e\u003cbr\u003eLow to Moderate — holds form in any flow, tolerant and adaptable\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"background:#eceff1; border:1px solid #cfd6da; border-radius:10px; padding:11px 13px; color:#22323a; vertical-align:top;\"\u003e📍 \u003cstrong style=\"color:#435760;\"\u003ePlacement\u003c\/strong\u003e\u003cbr\u003eRock-mounted — displays best elevated as a standalone centerpiece\u003c\/td\u003e\n    \u003ctd style=\"background:#eceff1; border:1px solid #cfd6da; border-radius:10px; padding:11px 13px; color:#22323a; vertical-align:top;\"\u003e⚙️ \u003cstrong style=\"color:#435760;\"\u003eCare Level\u003c\/strong\u003e\u003cbr\u003eEasy to Moderate — stable parameters recommended\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"background:#eceff1; border:1px solid #cfd6da; border-radius:10px; padding:11px 13px; color:#22323a; vertical-align:top;\"\u003e📈 \u003cstrong style=\"color:#435760;\"\u003eGrowth Rate\u003c\/strong\u003e\u003cbr\u003eSlow and controlled — grows organically into a more impressive colony over time\u003c\/td\u003e\n    \u003ctd style=\"background:#eceff1; border:1px solid #cfd6da; border-radius:10px; padding:11px 13px; color:#22323a; vertical-align:top;\"\u003e🧪 \u003cstrong style=\"color:#435760;\"\u003eNutrient Export\u003c\/strong\u003e\u003cbr\u003eModerate nitrate and phosphate uptake\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003chr style=\"border: 0; border-top: 1px solid #dde5e8; margin: 18px 0;\"\u003e\n\n\u003ch3 style=\"color:#6a6b58;\"\u003eSpecial Considerations\u003c\/h3\u003e\n\n\u003cdiv style=\"background:#faf8ee; border:1px solid #e6e1c9; border-left:4px solid #b7ad78; border-radius:10px; padding:13px 15px; color:#22323a;\"\u003e\n  \u003cstrong\u003eRed Coral Macroalgae is one of the most placement-flexible macroalgae available — its hard cartilaginous structure means it holds its form regardless of flow and does not require specific positioning to maintain its shape.\u003c\/strong\u003e Supplement with iron and iodine as part of a regular micronutrient dosing schedule to maintain rich crimson coloration.
