Starting to fill up 27gal tubs to fill up the new tank. Looks like something with glitter was in the tubs beforehand. Cleaning out as best I can, but no matter how many rinses and scrubs, always seems to be a few sparkly dots somewhere. Man, glitter is like.. well, you know what it's like. Anyway, I've managed to get it to where I don't see specks after a once-over, but that's not to say they aren't there. Any danger to the fish for a few small specks of glitter?
