I hated the playsand I rinsed each bag about 8 times and had about 250lbs of it in my 240 previously. It was nice after I got it to settle with the aid of some chem's and a few days with filtration. It wasn't bad but it was just to dark for me and looks sorta muddy I thought. I had it mixed with gravel for a natural look. It is cheap which is nice but the pool filter sand is cheap also and 1-2 rinses and its perfectly clean, granule size is a bit bigger also. I run the estes sand (expensive aquarium sand) in a couple smaller tanks and really like it but it was way to much for me to spend on my pond or 240. My vote goes for pool filter sand on a tank that size ~Trent
