There are numerous free-floating or swimming bacteria and algaes that can
accomplish blooms quite well if nutrients are available.  Dead bacteria are
not required.

If the tap water is very high in nutrients and/or the tank is immature, this
could be true.  But in general, the volume of water changes should in no way
affect the biological balance or equilibrium of a mature and not eutrophic
tank.  I find mature tanks quite remarkably stable, not a delicate
equilibrium at all.
