Hi All, I own several of these mechanical CO2 spinners and none of them like to stay suctioned cupped to the glass. They vibrate themselves off very quickly. Do any of you use these too? Anyone have a fix for the suction cups? http://www.aquariumguys.com/redsea-co2-reactor2.html?utm_content=redsea-co2-reactor2 Thanks Shango _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
