My local pool shop is awesome! They pass these old plastic sand/filter pool equipment containers to me for FREE. Pool and Mart Spa in Nedlands, Perth have the best customer service, and are just happy when these huge plastic filters get recycled and kept away from landfill.
I have them around my pool and even inside my home.
When I get time I will paint them to match my decor. What do you think? does your local pool shop do the same?
