Hi all .. i have recently found somebweird very tiny holes look curves in my tank glass eventhough they are not deep or anything and the only way to see it is by strong external light reflection.. the glass is 1.2 mm think and its a heated glass.. inwas wondering if its because of cleaning but i only clean mybtank glass with very soft piece of fabric or the flipper.
Sorry i couldn't take a picture for that its too smallnto take a picture
