I Have about 40lbs of sand I put into a rubbermaid container. It was live from a tank I took down. I want to use the sand again but obviously need to clean it and 'cure' it. What is the best way to go about doing that? I left it on my back patio for about 3 weeks in the weather....drained it and let it partly dry. I have rinsed it and drained it again....what next (besides the tempting "throw it out and start new") Thanks....
