Same! LolI'm running a 250w halide and t5. I did a large wc and stopped dosing amino just in case. I had this many years ago. It would only stay on a select few pieces. Whatever, I'm not going to stress it. I'll just observe and see if I can make sense of it. It is kind of tempting to pop the bubbles lol. I see them moving in the current.


.If anyone has a hanna copper test kit, give your tank a test. curious what level you get.
