i went to lowes to buy some rocks to put in my 40g then went to lfs
to get some silicone sealant to make a corner structure for my fish. when glue the rocks together i noticed that it was black in color, no biggie; it should dry clear this morning it still black. looked at the package for the sealant it says ,"3oz black" why the hell would a lfs
sell black aquarium sealant. LOL
and yes i did test the rocks b4 putting the in the tank and boiled them too. so there is 2 bucks down the drain.
