How can I assure myself that I'm covered for Pool liability

[Judah Farkas]

I'm going to be renting out a home that has a pool. The tenant will carry liability insurance but wanted to know if a pool needs a separate liability clause. I currently don't have a safety cover, just tarp with water bags holding it down. There is also a basic gate around it. 

How am I to know as to what extent I need to go so I won't be liable is god forbid something happens?
