It is actually made by Momentive now and was formally made by GE, it is caled Momentive RTV 100 series. It doesn't STATE food or aquarium safe but it is completely safe and is the most highly recommended silicone for adhesive strength for our applications. It is also only $8.99 for a caulking gun sized tube (10oz I think). I still have half the tube even after building my sump and installing my overflow wall.
