Tropic Marin Pro Reef Salt box 20kg

Tropic Marin Pro-Reef Salt in the 20kg box is a reef salt mix with calcium and magnesium provision and a comparatively moderate buffering level. The manufacturer specifies an alkalinity range of 7–8 dKH, making it relevant to reef systems already managing calcium and alkalinity through supplementation.

Prepare replacement seawater in a separate container with continuous circulation. Use it after the salt has dissolved and the water is clear, checking salinity and temperature before a water change. Choose the amount from your target salinity and measurements, rather than treating a package's approximate water yield as exact.
