Hi, I live in Nova Scotia, Canada right next to the Atlantic ocean. Can I use water from the ocean for a saltwater tank rather than mixing? Also could I use sand from the ocean as well?Question

personally I do not recommend this. first of all the water that you collect could be contaminated or it could cary desiese. secondly the sand could contain parisites and harmful critters. to use eather you would first have to sterilize them. boil the water and the sand for 3 mins? not sure whether its more or less. please correct me if I am wrong.

At my work we use natural sea water for all our tanks, but first it goes through a number of filtration processes. First the intake pipe for it is 6 ft under the mud so water is drawn through the silt and filtered mechanically and biologically by the organisms in the mud. Then it is mechanically filtered a lot more and passed through all your usual biological filtration stuff like bio balls. Its then pressurised in big tubs and stored for a while to let any particles sink and to kill off parasites. Finally it is put through a HUGE wet/dry filter and then UV filtered to remove algae.
You could do the same by storing the water in black tubs so there is no light coming in and just keep a filter in there with it
