Alright...
I have heard some seemingly conflicting info from numerous individuals about lighting...so I want to clear something up.
Specifically, I am wondering if it is true that 250-watt DE/HQI metal halide lamps put out as much or close to as much 400-watt SE metal halide lamps.
Now before you laugh, I know how silly this statement might sound since all I have ever read is that the best way you can judge the amount of usable light for invertebrates in the tank is the wattage of a lamp. So this would infer that a 400-watt ANYTHING (SE or DE/HQI) would produce more usable light for invertebrates.
And so you know what tank these lamps will be placed above... these will be used on my 300 gallon tank that is 36" tall which will house a mixed reef with mostly SPS, as well as clams at the bottom laying on a couple inches of sand. I want enough light so SPS could thrive throughout the tank and the clams would get a sufficient amount of light at the bottom of the tank.
FYI- I have tried doing a search on this topic, but for some reason the RC search feature is not currently working for me... so if you know of a good thread, you can also reference that as well.
