Any suggestions? I had a larger, straight PVC attached all day at about the same angle as post pictures and my small rbta didn’t budge. I saw that a 90 degree could help and had a smaller diameter pipe
so rigged another sponge and put in place yesterday. Still no movement. I twisted the tube to get a bit more light 2 hrs ago (this pic). Nada. I can see the little bugger at the base of the tube.
