>>Doesn't the skimmer remove foods for the LR?
No. A skimmer removes dissolved organic compounds from the water. High nutrient levels in your tank can lead to nuisance algae problems.
>>how long does it take for 'dead rock' to be colonized nicely by your LR?
My experience is that if you are able to maintain high calcium levels, the base rock (assuming it's made of limestone) will be covered nicely with purple coralline in about 4-6 months.
