    • Used it for years
Size: 200-Gallon
This stuff is pretty cheap and produces just as good of tanks as the more expensive stuff. Mix with RODI water and mix for at least a few hours before using.

    • Good for brackish tanks.
Size: 200-Gallon
Ok. I use this for my brackish water pond instead of straight sea salt as it has less NaCl and more MgCl and CaCl. Less NaCl is better for plants in the brackish aquarium and the higher mineral content is good for them. So reef salts are better for brackish tanks with brackish tolerant plants (Microsorum pteropus, Anubias spp., Cryptocoryne spp., Vallisneria spp, Ceratophyllum demersum , Najas guadalupensis, Lilaeopsis brasiliensis, Lemna minor, Aegagropila linnaei, Ceratopteris thalictroides, and Sagittaria subulata) that I have had success with salinities up to 10ppt. Like fish, the plants must be acclimated slowly (even more slowly than fish) unless they are mangrove plants that are tough as nails. I bought the SeaChem brackish salts and while they were friendlier for my plants I also had to use more to increase the salinity for the fish (scats, monos, archers, chromides, mollies, etc). If the primary focus is your fish with plants being secondary then either combine reef salts with some brackish salts or just use reef salts at a salinity that is good for the fish that the plants can also tolerate. If you are keeping your tank at 1.005 sg/7ppt (approx.) then maybe the Seachem brackish salts would be fine (you will still use more than the reef salt). However, at 7ppt using reef salts I have had no die-offs. I believe that even my monos and scats (my fish are between 6-8 inches and I see no ill-effect) will be fine as adults up to 10ppt using the reef salt along with the plants I listed above (my salinity fluctuates between 5-10 ppt as I have an outdoor pond and heavy rains and several days w/o rain can cause swings in salinity with the rise and fall of water volume). All-in-all you don't need the brackish salts and I think reef salts are better than normal aquarium sea salt for the planted brackish tank. Great info. My personal experience is that lemon bacopa does well only in low salinity (3ppt), along with water cabbage, african tiger lotus, and water spangles. Toughest (with changing salinity from 5-10ppt and temps from 68-92F) was valisneria, anubias, java fern, micro sword, java moss, guppy grass, hornwort, and wisteria. Emergent vegetation in my setup (2000gal outdoor, heated, green housed during Florida winter, pond) include mangroves (black, white, red, oriental), crinum, purple flag iris, giant leather fern, variegated pandanus and will be adding golden leather fern. ... show more

    • Salt is salt
Size: 160-Gallon
Used to use Red Sea Pro. Then moved on to Liveaquaria salt. Can't get that anymore so tried this. It works, haven't noticed any differences. This is much cheaper and ships free with Prime which is great. One of the questions Amazon asks for this review is how you rate it's "flavor". Talked to my fish and they seem fine with it; no complaints so far. LOL. ... show more

    • It's the industries most popular salt for a reason.
Size: 160-Gallon
I have been keeping Reef Aquariums for over 30 years, from the days when reefers salivated at what Julian Sprung would write his next magazine article. Instant Ocean is IMHO not the industry standard, there are certainly better salt mixtures you can buy but at the end of the day it will make very little difference as Instant Ocean is certainly good enough to keep any coral I have come across alive and thriving. I don't know why one guy is saying go to BRS for the salt. BRS is selling this for $63 while Amazon has it for $44 with free shipping if you have Prime. The reason this salt is the most popular is that it gives the greatest bang for the buck and while its one of the cheapest salts its still a very good salt. I am not a fan of some of the latest pharmaceutical grade multi mixture salts that require like five different things to be added in exact proportions to make a perfect batch of salt. It's too complicated and just an accident waiting to happen. I am a Fan of Red Sea Salt but at almost double the price per gallon of water and not seeing any difference in coral growth I went back slowly to instant Ocean. My tip to you is that when you make a mix of lets say 50 gallons of water you make sure to let it mix via the pumps for at least 24 hours and aerate it properly. Do not add salt all the way to 1.026ppm as the salinity will increase as the mix goes through the 24 hour cycle. I usually stop at 1.020ppm and then check it again in 12 hours and add more salt if needed. When that's done test the water for ALK, Calk and of course the temperature. Heat or Cool the batch to the temp of your tank and then test the Alk, Calk and Mg. If any of them are down from your aquariums parameters then add the needed components in small amounts until you get it as close to your tank water as possible. Typically with Instant Ocean I rarely have to add anything but sometimes it will be a bit low on the calcium side. Nothing earth shattering but just enough that I would feel better correcting it. ... show more
