A couple weeks ago these weird bubble things were on one of our return lines. I did a partial water change using our vacuum tube or whatever you wanna call it. Held the suction end at the return line as I scrapped algae and bubbles off. Thought I got rid of all minus one or two. Looked in the sump this morning and boy was I wrong. Is this a sign of the dreaded dinos?
