This stuff is really good for those people who are worried that the salt may be too high or too low. Their are so many good things about this it makes you think your fish are getting there nutrition . But it is pretty costly so check prices before bought.
This salt mix is pretty good! Me and my boyfriend have tried tons of different brands and mixes for our tank but this one is one of the best. We like it mostly because it clears and settles pretty fast so our tank isn't foggy for a couple hours, more like just half an hour or so. It also seems to be easier to get to the correct salt levels with this mix. Pretty good so far!
We have set up our first saltwater fish tank. We bought this salt mix because it was cheaper when buying in bulk. It mixed in with our water really fast making it easy to obtain the correct salinity level. We used about 1 bag for our 55 gallon tank. We were told it is good to have extra bags laying around because you need it during the monthly water changes.
While this is just marine salt mix, my answer would initially be yes. This product is easy to use and will help you reach your desired salinity. However, saltwater tanks are much harder than freshwater. I would recommend purchasing a hydrometer so you can measure your salinity.
