I think we can conclude the rock i received to be leeching PO4 and the reason for the crash.

Do yourselves a big favour, before adding any dry rock, leave it in a vat of PO4 NSW and after 3 days test the PO4 level. It may just surprise you.

It might be 25ppb PO4 ;P

And I am just too impatient to use dry rocks (maybe that's I don't like it?) and adding another lengthy step to setting up a tank.
