1. yes, strain them first though - see #2 as to why
2. no, the water will have elevated nutrient levels... not advisable to put into your reef tank
3. Amount of air is listed in the instructions: Air flow: Minimum 1.5 - 2 LPM (a good pump that meets that requirement is the Tetra whisper)
4. To keep the rotifers young. Old rotifers do not produce eggs thus kill culture counts over time. By harvesting 20-30% you will keep the culture statistically young. The ammonia control is dealt with via RGComplete.
5. yes, 11 ml of RGcomplete per 1 million rotifers, harvested, not what you are culturing. If you pull out 1 million rotifers in a harvest and you are doing a 30% daily change, you should have ~3,333,333 rotifers in the culture. If you don't need to harvest that many, cut back on feeding and your count will self adjust over time. For a 5 million rotifer culture, and harvesting 30% a day, you'll be harvesting 1.5 million and feeding 16.5 ml of RGcomplete.
If you see bubbles collecting and hanging on the surface of the culture, you're over feeding. If the culture is clear, you're under feeding.
