I'm new to UV sterilizers, but I was under the impression that the ammonia would still be present.
uv only kills the living.before or after the tower is fine.....i would rather run filtered water thru both the tower and uv......keeps the muck down
when starting up the tower leave the uv off for a couple of weeks.
never too much bio filtration !!!!
