to my knowledge there are 8 tropical marine tanks in tauranga not counting mine
most deal with wonderworld or get stock shipped in
additives are bought in bulk
online purchases are made for other goods etc
and they get flushed twice a day
get a chiller on that size tank or a nice cool spot to place it
