they look like small little dust particles, but i'm sure that htey're micro bubbles. but when i get close, they dont look like bubbles but just dust particles. they keep floating around and have been there since day 1... never settling. i didnt have them in my previeous tank. how is this possible? lol i dont see any bubbles inside my sump and i have a couple bubble trap baffles, no bubbles go into the return compartment at all. my tank's top is open with no canopy... are they particles? but why dont they settle? should i turn off power head for a couple hours and see what happens?

i put in a HOB filter for a few days with a filter pad and some cotton hanging on the tank not sump, still same thing.
