Owners doing regular weekly water changes on a larger tank get better value from the 500 mL size, which works out cheaper per litre treated (see the cost-per-litre table below). The 4 L pack is a big step up in both price and volume of water it can remineralise, so it suits multi-tank homes, breeders or shops running RO\/DI systems continuously rather than a single average display tank.\u003c\/p\u003e\n\u003ch3\u003eSuitable for \/ not suitable for\u003c\/h3\u003e\n\u003cp\u003eSuitable for restoring GH in RO\/DI, distilled, or soft\/rain water used for freshwater community aquarium top-ups and water changes.\u003c\/p\u003e\n\u003cp\u003eNot suitable for planted aquariums - Replenish's mineral salts include sodium and chloride, which can be detrimental to live plants; Seachem's own recommendation for planted setups is Equilibrium instead.
