HS Biology 32g Biocube build

I’m changing the water every 10-14 days. The coral loss happened prior to me buying the new light but it hasn’t improved significantly since having it.

The filter floss i change once a month sometimes a little more frequently. The chemipure and purigen I haven’t changed since March. All the parameters continue to test in range.

I think I have the light running for 12 hours since March (I’m only in class until 3pm). I believe the settings on the blue are one button press short of max. For white I think I’m somewhere in the middle, the tank has a dark purple hue to it.

You said Zoa heads were missing made me think zoa eating nudibranch
