I have a 125 gallon aquarium with a top frame....you know, the black reinforcing top frame. I have a Nicrew 150 reef light for it, but the frame is too big for the mounting bracket to go over....I could trim it so that it would slide over and tighten up to the aquarium wall. Is it safe to trim some off those top frames? I presume they are there to legitimate a somewhat thinner wall glass. Any ideas would be appreciated!
