Pack of 2 replacement suction cups for all Cal Aqua Labs drop checkers and filter pipes.
I ordered 8 of these sucction cups, hoping they would be superior to the cheap ones that came with my 4 sets of glass lily pipes. I struggled with the provided cups, which wouldn't adhere to the tank glass even after wetting with various agents and pressing in place for minutes at a time. When the new ones arrived from Green Leaf I changed out the cheap ones for the new GLA ones (no wetting necessary) and THEY ADHERED IMMEDIATELY. Thank you!!
