Hi,
I recently lost several of my acroporas to STN. They were doing really well, but I ran into a destabilization issue recently. I had a really bad briopsis infestation and treated with ReefFlux for two and a half weeks. Once per week I did a 20 gallon water change (it's a 75 gallon system, so that was pretty hefty) pre-dosed with new reef flux. The acros started to die about a week into treatment (sensitive ones going first).
While temperature wasn't particularly stable (worst spike was ~2 degrees due to controller error (which was user error, I should admit)). In addition, the die off spiked my nitrates and phosphates, with phosphates reading as high as 0.3 at one point and nitrates around 20 ppm (usually nitrate is not detectible and the phosphate is < 0.1, usually less than 0.5). That might be sufficient, but I feel like my acros have survived worse before.
So I sent off for an ICP test... Got some unexpected results in Tin levels and Copper levels, but nothing too extreme (at least to my knowledge). I would really appreciate it if someone could take a look and tell me if anything jumps out to them.
My acros continue to wither away, and it's really disappointing. My other SPS are not looking great (really lacking color), but aren't bleaching or necrosing like the acros. LPS seem unaffected (though one of my torches and one of my hammers are unusually swollen).
The sample here is from three 10 gallon water changes ago (I use tropic Marin syn-biotic salt), and things generally have been looking better since.
Any advice? RO came back completely undetected for everything.
