What Happened?

After a 76-day fallow period for ich, I reintroduced my fish to my Waterbox Marine X 60.2 about a month ago. The tank, running since November 2023, was upgraded with live rock that’s over two years old, transferred along with coral. I added three fish in the first week after fallow, and another three in the third week. My current stock includes:

- 2 clownfish
- 2 bangai cardinals
- 1 firefish
- 1 red blenny

This is a mixed reef tank. All my parameters have been stable and “perfect” during and after the fallow period:

- Salinity: 1.025
- Temperature: 78°F
- Nitrate: 9 ppm
- Phosphate: 0.08 ppm
- Alkalinity: 9 dKH
- Calcium: 400 ppm
- Magnesium: 1350 ppm

I dose 1 ml of All-for-Reef daily, 4 ml of phytoplankton, and feed frozen mysis twice daily. Despite this, I’m losing coral left and right, mostly SPS and two heads of frogspawn.

Five days ago, I dosed Reef Flux (5 pills for 50 gallons) due to GHA issues. I plan to bring a water sample to my LFS for algae identification on Monday, but I need help urgently.

I have only done a water chance once on the tank when I first got it and I just did another one for the first time as I did manual removal of GHA two days ago. This type of algae has been growing alongside it.

I take a turkey bastor and it flies right off into dust.

I have 2 power heads on each side, with a XR 15 G4 on for 8 hours blue purple spectrum.

Whats the problem? Flux is working. Algae is dying. Flux works specifically by inhibiting the production of a molecule crucial to cell membrane structure in the algae. So it makes sense that the algae is disintegrating as the cell membranes break down.

Issue is that, majority of my SPS has ben dying last few days + all my euphyillia has retracted showing Skelton severely. One torch has mouth gaping open.

I’ve heard of this with flux. Why I won’t touch the stuff. Run carbon and do water changes.

I’ve used flux before and I always have underdosed it for this exact reason. Interesting how everything is dying. My pink diamond zoanthids have died quick.
