So i just took the light and cover off of my 20 gal tall tank to put in a seeded filter cartridge. well, let's just say i wasn't thinking and i'm clumsy anyway, but i stepped on the stupid cover and cracked the glass. i am looking for a replacement ASAP because i do not want to stall my cycle. i found one for about $35 on ebay with shipping, but it included the light which i do not need. so i was just wondering if anyone has a spare 23" cover laying around for a 20 gal tall tank that would cost me less than $35 with shipping.. Thanks!!!!
