Increase in lighting/raise bulbs/fans/evap ?

[scubadude]

I currently have 2-175watt MH's 10k bulbs and one 40 or 20 watt actinic NO strip (its 4'long) I have bare bulb about 4.25" away from water line, with the new canopy that im building im making bare bulb at about 6.25" away and im taking out the NO actinic strip and adding two 4' VHO strips 110watts each one will be w/superactinic the other 50/50 I had one 4" RS fan cooling the lights Im adding another 4"er to the new hood as well, So i guess im asking if I move the lighting to 6.25" which is a 2" difference do i still need to change my photoperiod to acclimate? Maybe not as much? what does every1 recommend? Also im wandering about my evaporation now that im running another fan...Im at about 1.25 gal evaporation a day with just one 4" fan, how much more do you think I will evap?

evap will be a bit more, possibly upto the 1.5-1.75 gal area. mine is at 2-2.5 with 2 IC fans and 3 250w MH, plus 3 110w VHO.

As for light, no need to acclimate.
