The odd thing about UV sterilizers is the slower one pumps water through their unit the better they work. At first glance my 9 w. Turbo twist doesn't seem like a "giant killer". It is set however to 50g./hr. That is enough to run the 42gal. In my system past the UV around 30 times per 24hr. although the dinos don't move around much during the lights on period.
