Welcome @Pamela Mack !
Just one word of caution - that tarp will cut off the sunlight as well, so make sure you remove it during the day and let the light in. I would add some insulation around the outside of the tank - even just wrapping it in a few heavy blankets or some bubble wrap will help keep the heat in at night. Just a thought!
