    I have used so many salts over the years I have forgotten some of the ones that Ive used. I used stuff that ran me $120 for a Tall 5 gallon bucket (probably like 7.5 gallons) that was lab certified to be this or that. I started to realize that I kept buying different salt every time it was time to buy salt, one thing I have learned is that consistency does pay off. I dont know if this is the best salt in the world, but Im sticking with it. It is economical, it dissolves easily, my water parameters test good with it. I run a mixed reef with it and corals are doing their thing, fish are swimming, and everyone seems happy.

    I bought a bag for my saltwater tank. It works great and definitely serves its purpose. It was a great purchase.

    I opened my box, and their is an inch hole in the bag and the salt has drawn in moisture. I’m sure I can still use the salt because it dissolves in the water anyways. But when I opened the box, salt spilt on my carpet. I have ordered several bags of salt before and haven’t had any problems. Not sure if the bag got ripped open from handling or it was sent like this to me. Also noticed the heater I ordered was opened. I do have the heater plugged in and it is operating properly.

    I used to go to the Jersey shore a lot. I would navigate my way gingerly across the sand, trying to pick out a spot on the beach where I could lay my towel without being surrounded by discarded junk. A few years ago, I was able to relax there for a only few minutes before some muscle-head kicked sand on my face and stole my girl. I applied for one of those correspondence martial arts courses, and the next year I went back and confronted that same muscle-head with my new-found skills. This time, my ex-girlfriend held me down while he pummeled me. I would never waste my money on one of those correspondence martial arts courses again. This sea salt lets me mix up some ocean water for my pets without having to risk seeing that muscle-head or my bully ex-girlfriend at the beach. For that, its priceless. However, be warned: seagulls and beach pollution not included.

    I guess it must be ocean salt then. I didnt lab test it but it certainly is salt of some kind according to my salinity meter. I needed it for healing tanks and the red clawed crab that likes brackish water. It is ground finely so it dissolves easy which is great. So far, none of the pets disagree with it so take it for what its worth. This wasnt the most expensive one but considering I needed much less and it is salt from the ocean...its kinda pricey in general. Some aquarium hobbyists say you can just use kosher salt for a fraction of the price but ocean salt is supposed to be more beneficial for the aquatics.

    Ive been using Instant Ocean for over Thirty years. I started using it when I started my Hobby, when I became a research scientist and throughout the Thirty five years I ran an Aquarium business. I cannot recommend this salt enough.. Reef Tank, Invert Tank or a Simple Table top tank. Ive installed aquariums up to Ten Thousand Gallons, and as small as 1 gallon. They were all filled with Instant Ocean.. Now that I am almost retired?.. Getting it delived to your door for this price?... Priceless!

    Instant Ocean Sea Salt is my go-to aquarium marine salt for my brackish opae`ula (red Hawaiian volcano shrimp) tank, brine shrimp cultures and marine algal cultures. Ive never had a single issue with this salt. Its perfectly formulated and it has a lower total heavy metal percentage than most other aquarium marine salts on the market, including Reef Crystals (though all are safe when used as directed). It mixes very quickly, no CO2 injection required just an airstone or a filter agitating the water. If youre in the market for a low-cost, high-quality aquarium marine salt then Instant Ocean is a fantastic choice.
