MH lighting and scatches

[DEAD_BY_DAWN]

After my friends kid ran a muck with my algae magnet i have lots of scatches on the glass ,if kept totally clean i guess you cannot notice them so much (well i can but my roommate thinks i'm crazy as i point them out but anyways)i'm considering an upgrade in a few months from pc's to mh but i was told that even the smallest of scartches will show up under them ,true or false ? thanks ...
