Interesting. On my new Duncan, one head (out of three) is shrunk for a while, then opens back up. Could it be spouting another head?One of my Duncans is the canary. If it’s not extended I watch for a couple days. Usually it does this if it’s throwing off new heads or grabbed so food flying by but once an extended closure was from higher than normal parameters and sometimes the mother clown loves up on it and makes it unhappy.
Incredible!! Makes my wallet scream.Thanks I’ve got quite a few
