I've never seen a powder, I've only seen it in little bottles or foil packets.

I've only ever used the DA bottles (7/10) or the Hanna packets with liquid solutions (4/7/10)..I'm aware of the powered stuff you can get from hydroponic shops but have never seen it in a SW store. Meh

I think the bottles are more common in the stores and prefer those actually. I have seen the packets in one store although got mine free from ebay when I bought the pH pen (piece of crap) but they have to be mixed in specified amount of water which is a pita to measure.
