Hey all, could someone please help me? I have just acquired a 90 gallon hexagon tank and I would really like to make that into a planted tank for my angel fish. Problem is with the lighting though. I want to make an LED light by using LED chips but I don't really know anything about that. How powerful my light needs to be so that it would reach to the bottom of the tank? My tank is over 30 inches deep. I am not sure but it may be something in the range of 32. Could someone give me some pointers as to which type of LED chips I should use and whatever else it may help me in my new project? Thanks a lot!!!
