Getting Cyano after bio pellets is very common if you don't start gradually and you don't use MB7. The latter is very important to establish beneficial bacteria before starting bio pellets. The beneficial bacteria will out compete the Cyano when consuming the bio pellets or other carbon sources (like vodka).

But have to ask, if you have zero N03 and P04 why are you even using bio pellets?
