Here's the latest, and it's not good. I've posted this in the Emergency and Algae section, but am putting it here too for historical purposes.
For the past few days, my zoanthids have been all closed up, my leathers have shrunk up, and I have been getting more and more cyano (presumably) over the past few days. My crabs and snails have mostly stopped moving over the past week (but the shrimp are fine). I am trying to narrow down what exactly I have done wrong.
If this is not red cyano bacteria, please let me know.
Water paramaters are as follows
Temperature-78.5 (stable)
Salinity 1.025 (recalibrated to make sure)
DKH-9 (usually about 7)
PH- 8.2
Nitrates (undetectable)
Nitrites (undetectable)
Ammonia (undetectable)
Basic tank setup Max-E170 (40 gallon tank) with aquafuge 2 refugium, carbon, skimmer, ATO, and IceCap1k gyre (running at 10%). I dose Iodine 1x per week and put in 1 teaspoon of Kalk per 5 gallons of ATO.
Tank is 4 months old with 5 months old live rock (dead shrimp method).
Up until 2 weeks ago, the tank was stable. 2 weeks ago I bought a toadstool leather and a sebae anemone. I had difficulty getting the anemone to mount and drastically reduced the flow by turning off the Icecap 1k gyre. After a week of difficulties trying to get the anemone to mount, I took it back to the store so I didn't kill it. I tried to feed it a few times during this time. I exchanged it and paid a little extra for a finger leather coral, 2 feather duster worms, 2 scarlet leg hermits, and a bottle of Strontium & Molybdenum. My troubles started (I think) when I put my new goodies in and dosed Strontium & Molybdenum (1 cap full) and turned my gyre back on. I have also had an inconsistent experience with the brightness of the light in my fuge. Fish seem to be happy.
I am thinking hard and can only come up with a few possible issues that may be nuking my tank.
1. Strontium & Molybdenum overdose?
2. Too much flow?
3. Something unseen came in on the new acquisitions?
4. DKh is slightly higher than normal at 9 vs 7.
5. Fuge light being inconsistent could cause issues?
6. Corals unleashing chemical warfare on tank contents?
The only thing I can think of to do now is to do a 5 gallon water change every day for the next few days until things calm down. I would appreciate any thoughts you may have.
