What happens to the water inside in-pool Tanning Ledge furniture? Will mold appear?

Our in-pool products are rated UV16, so UV rays won’t penetrate to the inside of them. Algae and water organisms can’t live without oxygen and light, so as long as the water put into the piece was properly balanced and chlorinated, the water will stay clean. To prevent unforeseen issues, we recommend you drain the furniture and refill it with new, balanced and chlorinated water once a pool season.
