Instant Ocean Sea Salt (10 gal)

Great for fish only tanks. May be obvious to some but I learned the hard way that this salt doesn’t have nearly enough calcium or magnesium for a reef tank or to sustain coralline algae. Switch to reef crystals :)

Great value for the money! We use this for our saltwater pool in our hermit crab tank. We use 1 Tbs at a time since the pool is the minimum size recommended of a 2 cup capacity. This brand is highly recommended from all of the crab groups we are in. It has lasted for months and we are only half way through it. Will definitely be ordering more at the end of Summer.

You cant beat the price if youve got a sizable aquarium and do water changes regularly. This is the second case we have purchased for water changes and lately I have been the one maintaining our new 150 tank. Clean 5 gallon buckets, RO/DI that has had a chance to degas over a couple days and 2 level cups puts us right around a specific gravity of 1.021 fairly consistently. However with the new bags I did notice after agitation via a power head two out of five buckets (total of 10 scoops) had a piece or two or black debris. Did not investigate further but know it was not from the power head as it was freshly cleaned before mixing. I suggest sifting as you pour into your salt storage container to prevent any debris contamination from getting in your tank and possibly damaging the impeller on the return pump (if running a sump).

so the great thing about this, is I use to buy the 5 gallon salt buckets. MAN one drop of water in there and no you are chiseling your way through the chunks of hard salt now. This box actually has individual bags, so if one bag got wet, it will only affect that bag, the rest of the salt is safe. it happens sometimes when i use my scooper to put the salt into the RO water to make my salt water and a splash will hit the handle or the 5 gallon bucket and then its all over.. I like it better this way for me.

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.

I like the fact that I can buy a bag of this salt for 50 gallons on Amazon and have it delivered to my house for the same price of a small box for 10 gallons of the same product at the pet store. The mark up at the big box pet stores is ridiculous!!! This is my go to brand as it dissolves quickly and my water is always crystal clear after my water changes. Iv been using it for at least 10 years. Highly recommend!

Over the past 5 years, I have never ran into any problems with this brand. It delivers what it promises and It dissolves fairly quickly in the water. I have a 20 gallon tank and it takes half a bag to fill my tank. A full bag carries enough salt for a 50 gallon tank.

I have used this last for the past 8 years but something fishy with this last bag i used. eveything started to close off. 3 months of using it since i only have to do 5 gallon at a time. a fellow reffer Told me to switch off to another brand and see if theres any improvement. All my water premature were a little off but after using a different salt Everything is starting to open up again. Ive never complain about the soul since I had amazing results but this comes in and when you start losing everything in the tank.

Wonderful for jellyfish! Don’t waste money on mini packets of special Marine salt! Just use 1/2 cup per gallon of distilled water for your water changes. Specific gravity and pH are wonderful and I’ve been using this for months and the jellies are thriving!

Works great
