The fan over my sump is creating moisture (from the evaporation I assume) and a lot of things are getting ever so damp (including light strips!!!) Not a lot mind you but still..this isnt a good thing. I cut a peice of acrylic and put it over the end of the sump that the fan is blowing towards but that doesnt seem to be helping.

Anyone know of any tricks to keep this from happening?

The moisture is most likely building up because it can't be exhausted from the enclosed area fast enough.

I had a similar problem under my full tank hood, with the lights on the water would evaporate on condense on the Light strip reflectors. I added a couple a fans to exhaust the air at a faster rate and I do not have condesation any more.

You may have to exhaust the air out the back of your tank stand or something.

Mark,
On smaller tanks (less than 300 gal) you can exhaust into your living space but be aware that in colder climates during the winter your room will become quite damp. In my case I have aluminum window frames and with 80 and 90 gal tanks they would pour water off them in the winter. So much in fact that the jams were beginning to turn black and rot.
On smaller tanks and if you run gas, wood, or pellet heating this is much less of a problem as they dry the air while heating.

Another thing to think about when trying to remove air from an enclosed area is that you must also allow air to flow in. Preferably as far away as possible from the exhaust area (air is lazy and takes the shortest path to the suction side of the fan).

Just some things to consider,
