I have 2 165w Viparspectra lights over my 75gal, question being is i got a GSP frag about 4 months ago and it was fully opened for about the first 2 weeks. since than it opens up but not fully. I thought it would be just the stress of moving tanks from LFS and gave it some time to adjust. Still not opening fully and am curious to other Viparspectra owners if it would be more beneficial to reduce the time that the lights are on or to decrease the intensity which is blue at 50%. This is last case scenario before i just buy the 170$ par meter which id really rather not do because nobody around me rents them. Lights are 14in above tank. TIA
