Easier than phyto as I don't worry terribly about sterilizing equipment weekly. Super simply setup. I use a 14qt plastic totes with some plumbing (in hindsight, I'd go with
these). An air pump hooked up to a stone and some tubing to provide circulation. Feed them phyto fairly regularly. I keep tisbe, tigriopus and apocyclops. All separated as the apocyclops are voracious eaters and will outcompete the other two. They get natural sunlight from the windows, but I don't provide artificial lighting. I have to feed the apocyclops regularly. Daily in fact (I usually skip Sundays). The tisbe can go a few days and the tigriopus are good for about two days between feedings. I just dump in enough phyto to tint the water a bit and then move on. Occasionally I'll run it all through the spigot and then a series of micron mesh filters to I can then clean out the totes. That's a pita, but I only do it once a month (or more).
Here's a pic of my school setup. Tisbe on the left, then tigriopus and two totes of apocyclops.
