PFS IMO is crap, the only kind I get near me is clear BB's( I did buy some , used some, lost 2 fish to it( eating it due to shape)
I had this same sand in my big tank and the fish loved it, now thats out due to depth issues with the sand and straight flourite is in there andthe bottom feeders dont seem to mind.
Ran PS in my tanks and the barbells are huge and there has been NO damage to any fish due to substrate.
I went down this road when I first started using it, I am charging the camera( my good digi disappeared) and will get pics in a bit of progress, got sand in, heat in, filters in, UGF plate is out and Mopani is in w/ java moss clingers.
