I thought the culprit was phosphates as they spiked due to a busy life and changing my RODI carts a little later than I normally do. As in they spiked to over 0.90 according to my Hanna. I have it now at 0.19 and still going down. I had a cream angel that picked on these specific corals that are dying besides the Kenya tree. The cream angel was moved 2 days after being put in the tank as I caught him in the act. I also just upgraded this tank maybe a month ago? Maybe they couldn’t handle the switch? I had vipar lights and got radions for the upgrade.
Parameters are (double checked with hanna testers):
Mag: 1258
Calc: 476
Alk: 8.39
Salinity: 1.025-1.026
Ph: 7.93-8.1
Ammonia: 0
Nitrite: 0
Phos: 0.19
Nitrate: 5
Radon G5 Light PAR: 60(low points)-160(high points)
Edit:
I used phosguard for the initial spike - then added GFO yesterday (2 weeks later). I retested and the Hanna just blinked at 0.90 as it couldn’t read the level on the initial test. Then about 2 weeks later it was 0.19 after the phosguard. I did find it odd. I tested the RO water too for the initial reading and it also made the Hanna blink the day I got the high reading. Then tested the RO TDS which was at 14 and I NEVER let it go above 0 before (full time job, full time student, and have 3 kids). I just procrastinated.
As for moving everything I went from a 75 to a 90 and I switched everything over with the tank directly next to it. I used new sand but I used ALL the rock, media, and water from the old tank not to cause a spike in things as much as possible (water moved was about 95 gallons counting the sump so there was approximately 10-20 gallons of new water). I also added Dr Tim’s to try and avoid any cycle crashes for the move. I never had a bacteria bloom or spike in ammonia so I think that was successful. The biggest changes were the type of lights, miracle mud instead of sand in the sump, new sand, and the GFO.
