Salt Mix Comparison for Saltwater Aquariums

One of the most important components in a saltwater aquarium or reef tank is the salt mix. These days you will not have significant issues when choosing a salt mix. More than likely it is going to come down to availability and price for most hobbyists. Some brands are definitely more popular than others with some having been around for a long time and they do have very good reputations. There have also been a few newcomers to the salt mix market recently.

Of particular note is the price per gallon when buying already made saltwater or ocean water. Often times this is way higher in price per gallon than just mixing up your own. However, if you don't have a Reverse Osmosis filter or if you have a nano tank, the premade saltwater may work out better for you in the short run. Long term though you will save money just mixing your own using pure water from a Reverse Osmosis or RO/DI filter.

These are prices as found on Amazon in August, 2013 and I didn't include shipping costs. If you are an Amazon Prime member you get free 2 day shipping. Local prices will likely be somewhat higher due to shipping and handling to get to your local reef shop. The prices shown are just for the salt mix and they are in USD. Additional costs you should take into consideration for preparing your own saltwater include the RO filter purchase price and replacement filter media.

The best indicator here is the $ Per Gallon column. The lowest comes in at $0.25 (25 cents) per gallon while the highest is the premade saltwater coming in around $6.14 per gallon! Also keep in mind that some manufacturers may be using 1.020 vs. 1.026 SG when labeling how much saltwater a bucket will make. Therefore you should consider how concentrated the mix is, coupled with the price per gallon when figuring out the best mix for you. Target SG was found in the instructions for each brand's salt mix.
