How much salt do I need?
This calculator is meant for calculating how many pounds of salt is needed to mix inside a container of RO/DI water. We do not recommended mixing salt inside your aquarium as it may cause salinity spikes that will harm your inhabitants.
How to use this calculator
*Our Salt Mix Calculator uses Red Sea Coral Pro (our most popular salt mix) as the benchmark for its calculations.
Bear in mind calculations for other brands of salt will vary.
