I assume it is Cyano bacteria - but it's not going away. Phosphates are down to / at 0.03, it's the second treatment of Chemi-clean (50% WC in between after 2 days).
The purple would be coralline? I have some rocks that are 90% coverered with it. Looks nice, but do I want that much?
Trying to solve this issue before bringing fish back from QT in a month from now.
Also before buying anything else.
