    hi, i've got a light for my 10g tank, but its 40w which makes it 4wpg which is alot, would having it around a foot above the tank reduce the wpg?

    having it hight will reduce the light into the tank yes. if you dose higher and have a higher co2 level in the tank then it should not cause much of a problem. althought it will cause more maintanance
