I wouldn't say I'm a hater but the stuff I tried was a mess, I'm woundering if there is different kinds. John said his rinsed easy and the stuff I got was like Mississippi river mud once it got wet and was loaded with silt. The PFS I fugured was designed to be used in a swimming pool filter and turned out to be very clean so I stuck with what worked for me. The PFS is a lighter color then the playsand but once I mixed it with the TMS it looked really nice. My only knock against TMS is it is so fine you have to be careful vacuming because it likes to travel up the tube but mixed I find the PFS helps keep down a little. Either way any of the three will do the job I just found the play sand I bought was filthy.
