new tank macro suggestions

[ebojo]

I just recently setup my 75g + 20g sump. Other than chaeto, what kind of macro is recommended? Also, I am currently running 2x6W (9") T5's. The fixture came with a 10,000K and an actinic. I know that I am going to replace the actinic, but should I also replace the 10,000K? Looking at maybe like 2 x 6500K.

Any suggestions will be helpful.

Thanks
