I had one but it was finicky and I decided it wasn't worth the trouble and sold it. As the filter matured the sand would clump and the flow would be restricted. Then you would have to replace the sand. I was always fooling around with the water flow to keep the sand at the right level. It was a rainbow lifeguard model. Maybe others are better.
