Received one of those phone call this morning at work that all DIY tank builder just hate. It was the wife on the phone letting me know I had a leak all along the top of the viewing window . She told me that the carpet was soaked, the loveseat that sits in front of the tank was soaked fron where the water had been leaking from the tank all night. She said it was steadily dripping! I rush home from work and start to investigate and find that the screens on the overflows had clogged up and the water has risen to a level in the tank that it was not designed to go. It was more of an overflow then a leak. Needless to say I have removed the screens and cleaned up the water and life is good!
