I have a 46 gallon bow front aquarium. How many tablespoons of aquarium salt do I need to add? And can I keep the filter pads in the filter or do I need to take them out while I'm doing the salt/high temps?
I'd rather you worked this out; when I figure this I go through all sorts of "tests" to make sure I am as accurate as I can get, and then I stay on the minimal side just in case (meaning, slightly less salt than my calculations might suggest).
But some guidelines...your 46g tank with substrate and decor is more likely 30 gallons or less. The bowfront makes it a bit more complicated than a rectangular tank. If 30 gallons is accurate, this is 113 liters, so one level teaspoon [note
teaspoon, not tablespoon] being 6 grams, at 2 grams per liter, you divide 113 by 3 and get 37. I might consider the volume as closer to 25 gallons, and that calculates out to 95 liters, so divided by 3 means 32 level teaspoons.
This is a good site for converting imperial to metric and reverse:

When dealing with gallons, you need to discern US from UK gallons. As you are in the USA, your tank would be 46 US gallons, but less when filled as I said.
I have not read anywhere that salt and heat affect the filtration/bacteria. Obviously higher temperatures do mean less oxygen in the water, so adding more surface disturbance from the filter, or additional airstones or similar, is advisable.
