Still Among the Best Synthetic Marine Aquarium Salt after 5 Decades
I used to own a tropical fish shop, a commercial FW fish breeder and now just a retired hobbyist. I only use Instant Ocean salts to hatch and/or grow Brine shrimp now. I have always obtained superior hatches using marine salt mixes over rock salt. In the past, I've cultured some corals but a true measure of a marine salt mix is to have reef fish breed in captivity. I have had pairs of Yellowtail Blue Damsels, Chrysiptera parasema) breed almost every week for months at a time in the early 1980's. In a different setup in the late 1980's and early 1990's I had a 125 gal reef tank. Mostly corals with a few fish. In that tank, my pair of Pygmy Flame Angelfish, Centropyge loricula and trio of Mandarin Dragonets, Synchiropus splendidus, would regularly spawn just after the lights turned off. Of course, I never successfully raised any young because that is too difficult if one is landlocked with no access to tropical plankton to fee the young but some have been successful in tropical Pacific and Caribbean ora.com facilities. Most major public and commercial marine aquariums use Instant Ocean because it has high predictable quality at reasonable prices.

Great for a Reef Aquarium
My fish are alive and this stuff is easy to use. I can tell it’s legit because it’s exactly what my local fish store uses (They have a lot of healthy saltwater fish). I do mess around with the amount per gallon and I don’t use exactly what the recommend, but my salinity is always spot-on. I like the individually packed bags.

Great stuff, used for 40 years or so exclusively
I've used instant ocean for almost 40 years, from fish to reefs never had any issues.

Works good for 3 tanks
This is the 2nd bag we have bought in the past year for my son’s 3 saltwater tanks. It keeps the water quality and ammonia levels where it should be. This is quick to react and doesn’t affect the color of the water. Keeps fish tanks healthy. Will buy again!

No problems at all
I've been a saltwater hobbyist (45 gallon) for almost 10 years now and since the very beginning have been using this brand of salt with no problems at all. The pricing is always competitive compared to other name brands but the salt to me is always the same no matter which brand you go with. To mix this salt I use R/O water in a glass jar, pour in the salt and then fill with water. I shake it for a few seconds and let it sit till the salt dissolves. When the salt dissolves I start pouring slowly into the tank and measuring the salt amount with my meter. Other brand name salts that compare to this one are smaller grained and dissolve faster but for me, I have no issue waiting and I've noticed that on occasion over the years passed that if I do get impatient and pour some undissolved salt into the tank it doesn't seem to harm the fish or coral- some salts are not recommended to pour directly into the tank without dissolving first like I mention above in a glass jar with R/O water. Overall I favor this brand and have used it for so many years that switching now seems pointless. I'd recommend to others as I've had no problems with this product over the years.

It's salt. I use it for my hermit crabs. This box will last me 20 years. It does harden into a solid block but I just chisel pieces off, which is sorta fun.

buen producto que se disuelve facil con una bomba de agua/wave maker, buena calidad , el paquete esta perfecto para una cambio de agua donde se requiera 5 o 10 galones. En mi caso lo dividi en 2 partes y fue justo lo que necesite a 35, fue muy acertado la concentracion. lo seguire comprando para mis cambios en el futuro.

Not sure if it was due to moisture but the salt started to clump together

Acuario lomas siempre vende buenos productos a buen precio. Desafortunadamente el envío se hizo a través de la paqueteria Red pack y son muy malos, no quisieron entregar el paquete a domicilio por el peso del paquete, bien por acuario lomas y mal por red pack, mejor otra paqueteria
