So I am new to Led's and do not want to burn my whole tank up so what is the best way to switch from ATI t5's over to my reeffiltration LED they are epistar 2w each. My t5's do not have the uv guard on them so I have all ready went through a'lot just to adjust my system to them over 3 month's of slowly moving the light lower and lower each week with a screen over top. so how far should I start them out above the water the tank is 19 inches deep, and how many layers of screen should I use?
