starting aquarium with natural saltwater or premixed?


New member
I am about to start up a new tank. I have always used natural salt water to start up an aquarium but many people have been telling me it is better to use pre mixed to start it. I was thinking of having a holding container and mixing my own saltwater for water changes.

So is it better to start up an aquarium with natural salt water or premixed?
And if pre mixed salt water is the best- what would be the best brand for making pre mixed salt water?

If your going to collect your own salt water and use it for the aquarium, start with it. Just take the time to get your calcium, alk and all of that in order before putting anything in. I started mine like that, as well as my bro and both are tanks are doing great.
