Seachem Reef Fusion 1 & 2
Seachem Reef Fusion 1 & 2 are a widely adopted two-part liquid dosing pair that simplify calcium and alkalinity management for mixed reefs; their ready-to-dose liquids lower the barrier to consistent reef supplementation and are formulated to minimize precipitation when paired correctly. Compared with the multi-bottle systems in this list, Reef Fusion offers a simpler, often lower-cost-per-dose solution for hobbyists who want predictable results without the complexity of three-part regimes, while still delivering the core elements most aquarists need for coral growth.

Red Sea Reef Foundation ABC+
Red Sea Reef Foundation ABC+ is a three-part liquid system designed to provide a complete suite of major and trace elements for coral-dominant systems, prized for its standardization and lab-driven formulation that targets SPS-heavy tanks. It is technically more comprehensive than Seachem's two-part approach and typically commands a higher price, but offers finer control and element fidelity that many advanced reef keepers accept as a worthwhile investment for long-term coral health.

Review Summary
"Red Sea Reef Foundation ABC+ is praised for being a comprehensive, well-formulated three-part liquid system that supports strong coral growth, though reviewers note it can be expensive and requires strict dosing routines to avoid imbalances. Many hobbyists find it reliable for SPS-dominant systems when used correctly."

Brightwell Aquatics NeoNitro
Brightwell Aquatics NeoNitro is a liquid nitrate-control supplement that provides a carbon source and/or bio-stimulation for enhanced denitrification and nutrient reduction in planted and reef aquaria. Unlike the elemental dosing products above, NeoNitro focuses on reducing nitrogenous waste rather than adding calcium or alkalinity, making it a technical complement to those supplements and a cost-effective alternative to frequent water changes when nitrate management is the primary concern.

Two Little Fishies C-Balance
Two Little Fishies C-Balance is a targeted liquid alkalinity/carbonate supplement engineered for steady alkalinity maintenance with minimal pH disturbance, favored by hobbyists who dose peristaltically or need tight control without adding excess calcium. It fills a niche between full multi-part systems and single-purpose products: cheaper and simpler than some three-part regimes like Red Sea, yet more specialized than broad nutrient-control products such as NeoNitro.
