Help MetaL Halide ???

[sallen]

I am getting alot of water evaporation what is the required distance for a metal halide light(150w 20000k) to hang above a tank???The light also has 2 x T5 39w fluros as well.
One more thing I got an bubble tip anemone today. Just want to know if they remain closed up at first because it has not opened up yet and seems to be hiding in the rocks and has shrunk itself?
thanks

My bta has yet to open. He is about 3 weeks old in my tank. He just keeps on moving around. It is amazing how well they can get around.

Seemingly excessive evaporation is perfectly normal this time of year. In the winter months, the air gets really dry which only encourages it.
Auto top offs are one of the best ways to deal with this. Whole house humidifiers can also help as the higher the humidity in the house, the less things will evaporate. They save energy too...
