50-50 bleach-water is excessive. Usual recommendation is 20 parts water to 1 part bleach, or 10 parts water to 1 part bleach if you're kiasu. Soak for 24 hours is enough, 48 hours if you're kiasu. Thereafter, you can soak the rocks in water with antichlorine to get rid of as much bleach as possible. Dry the rocks completely to be 100% sure that you are free from bleach (bleach evaporates completely without residue). A small amount of remnant bleach on the rocks is not a bad thing as it actually raises your ORP until depleted. Vinegar will burn the surface off your rocks as acid reacts with calcium carbonate. Just use pure artificial white vinegar (5% acetic acid) undiluted to do this. Please note that this is a very dirty process as the entire surface of the rock is burnt off by the vinegar. There will be fizzing and popping while the reaction takes place, and the resultant residue is brown and smelly and damn disgusting. How it helps to reduce phosphate is that phosphate can bind with calcium carbonate and then leech into your water, causing phosphate problems. By burning the surface of the rock off, you are also burning the bound phosphate together with it. How effective it is depends on how much phosphate was bound in your rock. For example, I made the mistake of buying recycled live rock that was in another tank for goodness knows how long. Even after 1 round of vinegar treatment, the rocks are still leeching measurable amounts of phosphate (though much less than before). I would probably have to do a 2nd round of vinegar bath to totally get rid of the phosphate. However, as this rock is extremely porous and "holey" in structure, excessive vinegar bath would cause the rocks to potentially disintegrate or break into small pieces if too much of the surface is burnt off by the vinegar.
