Hi, I traded some fry for a 30 gallon breeder tank and I cannot get the glass clear. It has a "film" on each side of the glass an no matter how hard I scrub or use a razor it won't come off. Is there any special "Cure All" to get glass clear? Help would be appreciated, because without it, I will have to toss the tank and it was going to be my fun summer project
Thanks
Thanks
