Citric acid

None that I know of. I usually get mine thru amazon
This is where I buy mine, it's food grade at great price & usually at my door in 1-2 days-
Vinegar is acetic acid, which may* act as a solvent with some adhesives, such as used in some power heads.
Using the citric acid is less likely to cause problems.
Fwiw,
I wonder if those having such problems with vinegar used it full strength and/or for extended periods of time? Just curious.

Been using muriatic acid for soaks. Much faster than vinegar even at 10:1 ratio.

Just ordered a 50lb bucket from Duda Deisel. Thanks for that link @ichthyoid! Only $86 delivered to my door. A hell of a lot cheaper than any I've seen anywhere else.
add a sour dish to the restaurant menu - then you can but pallets at a time and be a wholesale resource for all of us.
I was just doing the math to figure out how much acid I would need to soak the dry rock I have. To make 50 gallons of water @ 5% takes a little over 21lbs of citric acid. With all the rock I'm going to do I'll probably need two 50lb buckets 
Not sure if it's worth it. I'm also not sure how fast it will react with the rock before it's neutralized.
*Edit* Well, since most of the rock has been in a tank already. It might be worth it as the cost of battling high PO4 for a year would be more time and energy than the Citric acid.

You might try using a 2% solution of citric acid for 24 hours then rinse.
Then put a piece of the rock in DI water for a couple hours.
Then measure for phosphate.
