I've got tanks with all the above types of sand mentioned, I think they all are pretty good. My 75 hap/peacock tank as pfs, looks good and really takes no cleaning at all IMO to put in. My 20g tall angel tank has tan playsand. Looks good in a SA tank, but takes some work to clean before adding to the tank. I also just set up a 75 for my frontosa for a bit and I used some Black Diamond blasting sand from Tractor supply co. I REALLY like that stuff because it takes no cleaning, and is a mix of black and tan so looks really cool, plus is big enough so the fx5 doesn't blow it around yet still small enough for him to sift and move around himself.
