is it normal that a new tank takes this much salt

[Mallory]

We are starting a new marine tank and seem to be using alot of salt and it doesnt seem to reach the correct amount in the water (1.025).... is it normal that a new tank takes this much salt... Almost 17kgs in approx 300litre tank??? we have sump , protein skimmer , chiller and heater.

What are you using to measure the salinity? The most accurate way to measure it is to use a properly calibrated refractometer.

we are using a floating hydrometer...

What's water temp

 

[Mallory]

26 degrees celcius

In English u have roughly 37 lbs of salt in a almost 80 gallon tank ...so 8tbsp per 128oz (1gallon) is what u need u should not be measuring by weight but volume such as oz cups tbsp etc most can't acurately achieve correct salinity going by weight
