all great questions! I personally dont rinse macro before getting rid of it, I'll dip it in and out of the water, do a little shake, and the hokey pokey in the water while removing it but otherwise I'm not too concerned.
as far as actively harvesting I guess my question would be do you have a reason to? Typically they will find they're way into the display without problems (unless your running a needlewheel pump) and you will already have a pretty well established population in the display already. If you want to you can, but it might be easier to farm them elsewhere and let the
sump critters stay
sump critters... they do good there!
On the separate tank and harvesting... Welcome to what could be an addiction...
you could build a "pod collector" using a jar, a powerhead, some airline and screen as I used to. Scraping them off typcially damages them and doesnt do you much good.
I've since found that manually siphoning using a peice of airline tubing and directing the tube to what I want to suck up has been pretty much the easiest way to harvest. If I'm harvesting from a culture and don't want to carry around the high nutrient water i'll use a 53um or a 250um plankton collector from
http://florida-aqua-farms.com to catch the adults and dump the culture back in.
The jar with powerhead and tubing was more of a goofball experiment that I thought twice about posting, it was quite the difficult to use contraption he he. I've found the squeeze pumps like those for camping kerosene and such work very very well, and probably the easiest thing I've found is to culture the critters in jugs with spigots at the bottom so no actual work is involved in hunting them down, just open spigot and pour! (in pointer to your first thought, your on the right track but yeah... that 10 was probably a lot handier than a new container)
I think I might have pictures or something up on the copepodgeek site
Copepod Culture Handbook (slated for rework) | handbooks but that paper was drug over from a much earlier version and is in desperate need of rework... maybe I'll do that this weekend before the madness of reefstock hits next week.
