can i use regular hardware store silicon to glue rocks together? im also planning to use the silicone to glue some filter floss pads to the old filter media holder.
let me know what you guys think... need some advice real quick. thanks in advance.
check the diy section, big post at the very top on silicone. You can use normal silicone but make sure that their are no antimildew chemicals added to it. These mildew resistent silicones will definately harm your fish. GE Silicone I works great.
