Yeah 2 should be fine. How hi are they from the water line?
Hi I'm now running 68 blue from 14.00-2300 and 25 white 15.00-22.00 so blues on thier own an hour either side. I'll post an up to date photo later as need to clean the glass first as it's been over a week now and having to soak my glass cleaner to get coraline algae off.
Just be careful not to crank them up too high too fast. I am working mine back up to these settings over a period of a month because I'm an idiot and decided that as 90% of my corals were thriving I thought I'd turn them down to a lower setting to see if it would help my frogspawn coral but all that has done is p off my red montipora digi. So it's going back to where it was happier. I'm aiming for 80/25 blue to white. Can i ask what coral is it you have? And do you have a shot of your set up? I've cleaned my glass and just waiting for the water to clear then il pop up a pic.
They are quite bright/powerful so start lowish when you get your first nem.
Hi, as far as I know no you can't put a wide angle lens on it but a diffuser is possible with light diffuser cut to size then double side taped on to the light. Also as the fitted lenses are 90 degree lenses removing them (which is really easy if you are happy opening the unit) would make it 120, but you won't get as much depth penetration but with a 16inch height shouldn't be a problem as they are powerful lights. the lenses are easy to refit if you don't like it. Just experiment with certain lenses on or off as in try with just the outer edge ones off and see if the spread is wide enough and go from there.
