400W MH's inhibiting Photosynthesis......

[StirCrazy]

when exposed to light intensity generated by higher output lighting systems (400-watt metal halides, 4-96 watt PCs).

<font size="2" face="Verdana, Helvetica, sans-serif">Is Dana sugesting that this "Saturation level" can be reached with 4-96 watt PC's. if so this would also sugest that they put out MORE usable light than a 250 watt MH. Also that this amount of PC lighting is usable for high light Corals. If this is true you can get rid of MH lighting and lower the heat transmision to your tank.

just a though
