Hello,

I am about to replace the 6 x 55w bulbs on my 100g tank. I was thinking of reducing the wattage from 330w to either 292w (4 x 55w 7800k + 2 x 36w 6700k) or 254w (4 x 36w 6700k + 2 x 55w 7800k).

I am reducing the wattage as I am sick of fighting algae.

Unfortuantly I would love to get my hands on the GE 9325k bulbs but we cannot get them over here in Australia and I cannot find anyone in the US to ship them to me.

Has anyone used the 7800k bulbs and would they look ok mixed with the
6700k bulbs?

Thanks,
Dave.

The 7800K's are the first and only PC I have used thus far. In most pics on the net that I had seen, the 6700k's were too yellow and 6700K + 10000K looked like a good combination. So it just made sense to get even bulb coverage with a spectrum approximating that I which seem to prefer based on the 6700K + 10000K combo.

I would like to some day try the 8800k, 6700k, 10k, and 9325k

Regards,
