uv filter

[steve.bridges]

i purchased a laguna powerclear 1000 uv filter after talking with the guy in the lfs, he said it may help control algae. does anybody know anything, have any experiences?

i,m worried it may kill off the phytoplankton and other coral feeds, nutrients etc


i have a 45g reef with leathers, brains, xenias, gspolyps, tons of critters and a few fish.
magnum canister filter 350
2 ph
50lbs live rock
2inch sandbed

cheers
