Anybody remember thread someone posted showing detail of a DIY screen over tank using netting. I cannot seem to locate. I am wanting to get rid of my egg crate over the tank and replace with screening. I am still trying to figure out what to do around my overflows. My return is higher than the top of the tank, plus there would be a 1 1/2" gap between screen and overeflow. I now have baskets made from eggcrate over my overflows.
