Free reef tank budget calculator. Enter tank size + build tier, get estimated cost breakdown for tank, stand, sump, lighting, flow, skimmer, ATO, controller, and livestock budget.
Reef build cost scales with both tank size and tier choice. The classic mistake is buying a budget skimmer or budget light for a premium tank - those become the bottleneck for the entire system. Spend on the lighting, flow, and skimmer; save on the stand and aquascape.
Browse the full calculator library for tank stocking, water change, dosing, PAR, electricity cost, heater sizing, CO2 BPS, salt mix, and more.
