Oops.. Too much consideration already, not faded to drive your BMW.
Anyway feel free to PM me if you wish to test drive my 5D3 with choices of 3 L turbo lens specs.
Mind PM me the price of your 48" Honda of the Pharos Led? What's the turbo driven wattage?
WOW, this is really some god-like discussion here! Keep it going yea!
Anyway just to chip in why sps turns brown are:
1) Lights
2) Nutrient Level ie. PO4 especially
Imo, those 2 above are critical to maintaining a thriving SPS tank. Low lights can cause SPS to lose color while high nutrients can also cause the SPS to brown out.
