Thank you so much for all the advice. I don't even know where to start.
Testing I tried to download the Aquarium Note to a form everyone could read. I can't figure it out. PH has been 8.1 to 8.2 since 11/2022. After the tank cycled my nitrates started at 25 and stayed there, lowering after water changes to 10, dropping to 2 while I started doing 2 water changes a week and rose steadily to 25 until I started adding vodka. I tested Monday, nitrates are 15. Phosphate since 11/2022 started at .03 and has held steady at .025 since. Alkalinity has been 8.3-8.7 since 11/2022. Magnesium 1420-1440...however when I was fighting this hair algae I purposely elevated magnesium to 1520. It is currently 1440. The ICP test, the last one was in the green for everything but arsenic. I am mailing off my water tomorrow. New test. Both RO and Main.
I am using Nyos salt. They send each bath off for ICP testing. I have used IO, Kent, Brightwell, and Red Sea. Red Sea was so horribly inconsistent. Unless you take that bag out and roll it all around then it's bad. Also left a brown substance on everything. Like a mud. I was cleaning out that brute monthly or more!
I am using the Reef Breeders Photon V2. Par readings before coral were 300 at surface, 210-235 in middle, and 95-110 at sand bed. It ramps up and down and is on for 12 hours with a four hour peak of 35 blues 10 white.
The GFO and vodka dosing is because my tank was over taken with hair algae. The corals were suffering. Although nitrate and phosphate looked ok I knew that the algae was sucking it up. All the efforts I made actually really worked. Corals appeared to respond favorable until they didnt...
I have tested for copper. It's not showing up in main or ro water. Our house was built in 1895. So I wouldn't be surprised if there was arsenic and copper and crap. This is the red sea copper test.
The reef is mixed because I got a bunch of free crap. I always had softies and montipora and everything was fine. The xenia lived on an island, the clowns hosted it, until the first crash. In all these years there has been times when the tank was perfection. I look back at all my notes and see NOTHING that would explain the crashes. Old notebook I flipped through, I was using IO and kent back then. Mag was 1500+ and calcium was 500+ but everything looked great. The first crash was sudden. I moved the fish to a rubbermaid and watched as overnight all my corals died. This would happen over and over again.
I really don't want to dose carbon, I was just hoping that maybe it would knock this algae down so these corals can breathe. It has but the corals are no better for it.
So I took some photos of the tank. Well what's left. Much easier with lights off.
