Tank crashing?

[OpenOcean33]

So over the past week I noticed that the tank has not been doing good. I have no idea what could be going on with the tank. Two weeks ago I lost my Duncan but I thought maybe it was from a minor alk swing I had before. It had been hanging on for some time about 2 months. Now since last week my tank has been deteriorating at a fast pace! My hammer lost one head, my montipora died, anemones are shrunk, half my zoos are not opening and everything is going to hell. My fish appear fine. My parameters are salinity 1.025, N- 3 P-.03 C- 390, M-1480, Alk- 7.2. My tank should be stable as I haven't touched it in a while or made adjustments. Im nervous I am gong to loose my whole tank. I did two water changes 20% each last one was last night and changing carbon out every 3 days. What else can I do? I do not currently have another tank to put them in. Oh and there is a little cyano in a corner of the tank... could this be toxic I can imagine it would do this kind of damage.

Are you using an RODI unit. Maybe needs to be changed out.

What is your pH?

My first guess would be a water issue.
Possible your water co is adding something new?
Aerosol contamination?
Bad batch of dosing chemical or salt mix?
Electrical current in tank?

I do have an RODI unit, its reading 0tds. However maybe the gauge is broken?

That I will have to check, I didn't check that this morning. I will get back to you on that one.

this thread is the best example of forcing regrowth on a tank Ive seen. he literally turned it around without delay.

if your tank is large and this job would be hard, price of large tanking I guess. its at least mighty rare to have a start to finish arrest loss phase and forced growth phase on file just closed out last week. fall back on this if nothing else works

he did it twice over in one thread. best one yet.

Nuvo 10 Crash?

It only needs another normal rip clean Rocks only touch saltwater and are rasped clean externally and then light peroxide on former invaded spots, all dentist quality detailing done externally Try to avoid coral flesh areas but like a dentist does to gums, work right up to them and debride...

the reason that method is amazing is because you can run it on a perfectly healthy tank and it makes it work better, not worse. its a total reset of params, that way any bad ones are caught up and rebalanced.

if you run it on a problem system you're using the ability to instant recycle without losing filter bac and saving massive time and wait. if you run it on a clean system it simply removes waste and makes the tank live longer, less invasion etc. its a work heavy method, but ultra solid biology hence the work application thread.

I have been using the same salt for some time about 4 months. I can check for an electrical current, maybe something new in the water. I don't believe aerosols because everyone knows to be careful, however, accidents do happen.

Find out the problem then make changes. Making changes that don't need to be change cause more problems.
90% of the times its a swing in parameter (mainly ALK) that causes issues. Don't assume the problem will fix overnight.

So I got to retest everything again today and Salinity 1.025, Alk7.5, Cal- 400 N-0.50 P- .03 Mg - 1480 and newly ph- 8.1. So I don think its a chemistry thing. Still have to rule out bad RODI expect ads meter is 0. I have yet to check stray voltage, no rusted parts that I can visually see. Maybe it was an unseen alk swing The birds nest is taking a hit now as well and kind of peeling away its outer layer to a white skeleton. So odd, Im stumped but will keep looking for other possible contaminants. I am moving the tank next month so I was expecting some loss or disturbance but not before ! lol
