Tropic Marin Re-Mineral Marine 250g

A complete mineral reconditioning powder that restores all the essential minerals and trace elements lost when using reverse-osmosis (RO) or very soft tap water. It replenishes calcium, magnesium, potassium, sodium, bicarbonate and carbonate salts — along with trace elements — to recreate natural seawater conditions. Simultaneously it increases and stabilises carbonate hardness (KH), making it ideal for preparing water for marine and reef aquariums.

It’s particularly useful when topping off evaporated water or preparing new water for water changes — ensuring the added water doesn’t dilute or destabilise your tank’s mineral balance. The formulation contains no phosphates, nitrates, or sodium chloride, so it won’t fuel algae or disrupt salinity.
