Hey everyone... my husband tried making a top for my 240g long tank out of plexiglass. It worked really well at the beginning, but now a month later, it is bowing and when he tried to fix it, ended up cracking it. What I am looking for is something he can maybe custom drill or cut so that my pumps and cords can all go through it, but I am looking at killis for my tank and I know that they jump, so it needs to fit well! Has anyone had luck ordering a top? Or is there a place someone can recommend I look?
