| Re: making sea water or just buying it problem with my LFS is that the water they sell is also the water that is currently running in their system, they have a 2500 gallon holding tank that runs water through it constantly. the problem i see with this is that if they have a diseased fish then the disease might be in the water and get in your tank... basically the same reason you wouldn't add the water out of a fish bag into your tank |
