many fw tanks go through a bacterial bloom during the initial run in phase, usually turning the water cloudy grey, sometimes being so 'bad' the water can get to where it looks like skim milk

let it run it's course-once the bacteria finish feeding off of whatever organics are feeding them, the bloom will crash

typically the bloom slowly gets worse, and then crashes over nite, w/no previous indication it's done

it can take awhile to run the course though-adding some munge from an established fw filter (squeeze out some old yucky floss from a running filter) usually speeds up the clearing process greatly

8 hrs of good light is all you need-the rest is just extra revenue for the elec. co.

I find that stopping a bacterial bloom in it's tracks with UV doesn't keep it from coming back in many cases. It's a natural process and if the nutrients are building up because there is still insufficient bacteria in the filters these will come back or cause different problems because nothing is feeding off them. I'd say ride it out like vitz suggested.
