What salt to use in a saltwater aquarium? I have found when reading forums on the topic that many people use whatever salt is cheapest, or whatever salt works best in their tank with their fish and corals. There are quite a few brands of salt that seem to be popular with other hobbyist such as Instant Ocean, Tropic Marin, Reef Crystals, and Coralife to name a few. Preuss Pets had a couple brands of salt when we inquired; Instant Ocean, a brand with a long history and high popularity, or a newer product, Seachmen’s Aquavitro Salinity.

We chose Salinity because it came highly recommended, even as a newer product, and the price was equivalent to the same size bucket of Instant Ocean.

One thing we liked about the bucket was the screw on lid with recessed o-ring. Most salt buckets have snap on lids, which are easier for moisture to get in and clump the salt, making it harder to dissolve. We liked this new lid  immediately and found that it is new from a salt manufacturer and wondered why this hasn’t been done before. From reviews, other hobbyist share this sentiment.

The main thing we liked about Seachem’s Salinity is that each batch of salt is laboratory tested and guaranteed to meet the parameters listed on each bucket. From my reading this is a also a first for aquarium salt manufacturers.

The reason that knowing what parameters are in each batch of salt you are using is important because when you create synthetic saltwater for the aquarium, you are trying to mimic natural seawater as close as possible. Seawater contains many major ions such as magnesium, calcium, and chloride as well as minor ions such as bromide. There are also more than 70 trace elements which are essential for the organisms you will put in your aquarium. This is why it is important to know you are paying for and using a quality salt that mimics nature as close as possible. Some aquarists add supplements or “dose” their aquariums to help  target the levels found in natural seawater. Using a quality salt will help to decrease or eliminate such dosing.

A salt manufacturer that guarantees their salt by laboratory testing shows me that it is a high quality salt, a must for a great saltwater aquarium.

The salt is very fine, almost a powder, and dissolves quickly. We also have not seen any reside in the mixing bucket.

We have no previous experiences with other brands of salt, as we are new to the hobby, so we cannot give a comparison with other popular brands. Overwhelming positive responses from forums and blogs on the topic make us think we made a good choice for Seachem’s Aquavitro Salinity Aquarium Salt.
