Chiller Question

[bigsink]

I have a 75 gallon reef tank and 40 gallon sump with 2 175 W MH. The temp is slowly getting out of hand. It ranges from 81-83 when the lights are on. I get around 3 hrs of MH light before the Controller turns the light off at 83. I would like to keep the tank at 79 or 80 and get 8 hours of lighting. I am concerned with my SPS not getting enough light. This has been the case since June. I put an AC unit in the room, but it did not do the job. There are no windows in my fishroom to vent a portable AC unit properly. AC ran 24 hours a day and did not keep room under 83. It was a 9000 BTU unit in a 200 square foot fish room. I now want to go with a chiller. The ambient room temp is between 80-84 all day in the summer. I have fans running over the tank and the canopy is very well vented. Can anyone please chime in with chiller suggestions. Does a chiller need to have a place to drain like an AC unit? Would a drop in unit be better than a flow through unit? Price is not an issue, I just want to do the right thing. Thanks!

If I had to do it again I would get an in-line chiller and have the chiller away from the display tank, they are quite noisy. But I have not had any issues with condensation.

If you have a fish room where noise isn't an issue a drop in unit would be fine.
