Bacteria bloom is NOT the beneficial bacteria but other micro-organsms that thrive in your tank and cause no harm to fish. Don't worry about it, it'll clear soon enough. The beneficial bacteria grow and multiply much too slowly (unfortunately) to cause a 'bloom' they also don't live in the water but in the substrate and filter media (which is why water changes actualy do NOT effect cycling provided the water is de-chlorinated; whilst gravel vacuuming and changing filter media can and does effect your beneficial bacteria).
