Too Much Carbon or HCGFO?

[ronau]

Hello,

I'm planning on running Carbon and HCGFO in separate reactors on my new, and first, marine tank. According to the calculator on BRS, I should be running 0.63 cups of Carbon and 0.78 cups of HCGFO. Are there any problems of just rounding it up to 1 cup of each?

Thanks,

Ron
