I saw no effervescence and the prints were no weak at all. Perhaps, it has something to do with the order in which they are added. As a general rule, I start with FO or AFO then add my pt, then pd, then what ever contrast agent to the mix. But once again, I use Platinic Acid, which is the same except for H in place of Na.

I have found that mixing Ammonium Ferric Oxalate with NA2 causes a yellow insoluble precipitate and effervescence on mixing.  The resultant print is very weak. 

NA2 with Ferric Oxalate works fine for me.
