Hello. I have two Vipraspectra 165w black boxes. I’m thinking about taking off the filters to help with spread. I can only mount them about 6.5-8in above water. I’ve heard of people removing the filters to help with the spread but I wonder what I’m sacrificing doing this. Does it impact PAR efficiency? Will it change the intensity? They look like little magnifying lenses. Has anyone else done this. I’m a DIYer and am always looking for ways to modify/improve what I have. Thanks for any input.
