for a small tank it's fine to use. depending on the size and frequency of the water change, as the tank gets larger the NSW will get more expensive and heavy to carry.has any body ever use this product before seems like a good idea saves time and effort and is real sea water and not synthetic. any advice would be appreciated thx in advance.
Not sure how "catalinawater" is doing(like would it get stale) in the petco and other retail operations but in commercial operation such as a lot of the fish wholesalers and breeder networks, it is one of the greatest water you can find. A lot of the public and scientific aquariums use their water in US. My fish usually comes in their water and I am one happy customer.
