Yeah, I think the precipitate is smaller than 10 microns. I'd just run it straight into the skimmer like biopellets. Like I said, I've never used it in a running system before, but my understanding is that the sensitivity to fish is only if the water becomes cloudy with the precipitate which is why people recommend to drip it instead of dump capfuls in. Some people I've seen running it drip into their first sump chamber and assume that the precipitate will settle out by the time it goes through the sump. My sump has about 6x turnover through it, and I don't think anything that is 10 microns or less is going to be settling in there!
