265g reef slowly dying

[Freddie83]

Hi everyone. I’m in desperate need of some advice. Tank has been running amazing for months on Reef moonshiners. As of lately.
I’ve been watching my corals slowly STN and recede for roughly 2 months now.

My po4 has been in check for about a month (it continues to increase on its own but I keep adding phosphate rx and I’ve also added bio pellets for a long term solution).

The only other thing that jumps out at me is the sudden increase of Tin in the water.
I’ve checked all pumps and magnets and cannot find anything rusting out.
Any thoughts or ideas? Thank you!

That’s the newest one? Only thing that jumps out at me in that one is nitrate. Unless your corals were acclimated to that level I would expect some browning but not sudden deaths.

Waiting on a new one that should come in this week

Nitrate and phosphate are quite high. I would start there

Have you done any water changes to bring down nitrate and phosphates? What are you dosing/feeding?

Run an Aquabiomics DNA test to see what pathogens might be in the tank. I had same issue that took mine down, antibiotics can help but need to know what you’re fighting. It takes a few weeks but the results will be super informative…
