I let mine settle overnight before I use it. I mix 5 gallons with 10 teaspoons, run a powerhead foir a while, cover it and let it sit. The sediment will settle by the next morning, leaving the solution clear. I use a pitcher to skim a gallon from the top, add it to my makeshift top off unit, and then let it sit in there for a while so any sediment I did pull up will settle. Then it's a slow gravity drip from the resevior of just clear solution. You can use a pump but be sure it is raise in the container so as to not pull up any sediment.
