6700k or 18000k

[jorjef]

The facts

I know 6700K is more in line for fresh water planted tanks but is there going to be that much of a difference compared to 18000K based on the following


20" water depth
Lps and softies

I have run only the 18000k bulbs from the start but wondered what I will loose buy going to 6700K. Also any benefit in running a combination of the two or stick to one or the other.
