Reef aquarium gear, independently reviewed
Honest picks for reef lighting, protein skimmers, return pumps, salt mix, test kits, dosing systems, and controllers. Structured around your tank size and upgrade path, not which brand paid us.
The cover pick
reef lighting
The best single-fixture LED for tanks under 24 inches square. The consistent real-world SPS coral growth it produces justifies the premium price for any serious reef build.

Top Pick
The standard against which every other reef LED is measured at the 24-inch coverage tier. The G6 generation introduced the HEI2 hybrid optic system and pushed deeper into 395nm UV for coral fluorescence. At 100 watts with a 24-by-24-inch even-PAR footprint, the XR15 G6 Pro drives mixed reef and SPS corals from softies to Acropora without hotspots.
Best for Mixed reef and SPS-dominant tanks from 24 to 50 gallons where even PAR across the full footprint matters more than cost.
2 The EcoTech MP40wQD is the standard against which large-tank wavemakers are measured. A magnetic-drive, through-glass propeller that moves up to 3,500 GPH through a 0.5-inch glass or acrylic panel without anything in the water column except the wet side disc. The QuietDrive motor with Mobius app integration produces programmable wave, pulse, and tide simulation modes.
Best for 75-gallon and larger reef systems where the clean aesthetic of a through-glass drive is worth the premium, particularly tanks with demanding SPS corals that benefit from high randomized flow.
3 The larger sibling to the XR15, the XR30 G6 Pro covers a 32-by-32-inch footprint at reef-quality PAR. With the same HEI2 optics and 95nm UV spectrum as the XR15, it is the premium choice for 75-gallon and larger systems that want single-fixture coverage without light gaps at the edges.
Best for 75-gallon and larger reef tanks, particularly SPS-dominant systems where a single fixture needs to cover the entire footprint at SPS PAR levels.
Best Value
Red Sea Coral Pro Salt is the most widely used reef salt mix in the hobby for good reason. Naturally harvested from the Red Sea, it mixes to elevated levels of calcium (450 ppm), alkalinity (12.2 dKH), and magnesium (1350 ppm) that actively support coral calcification rather than merely maintaining baseline seawater chemistry. Available in 160-gallon boxes and 175-gallon buckets.
Best for SPS-dominant and mixed reef tanks where elevated parameter support from each water change is part of the coral maintenance strategy.
5 Tropic Marin's Pro-Reef is a German-manufactured salt formulated with elevated reef parameters and their proprietary trace element balance developed from decades of laboratory research. It mixes clear in 12 hours with adequate circulation and produces a stable, precise chemistry profile that is a favorite among high-end SPS reefers who want consistency above all else.
Best for Precision SPS builds where chemistry consistency between batches is a priority, and for reefers running ICP testing who want predictable baseline parameters.
