290G Peninsula Tank

What is your NO3 running at? Also do you dip the sps to see if anything "strange" happens to come off them?

So my NO3 has been tested by two test kits. API which showed zero and Salifert which showed just above zero. In case I had issues that i wasn't detecting, a few weeks ago I started with Biopellets (though a minor amount). This was well after corals started dying in mass.

I have searched corals for pests but can find none. My frag tank is attached to main tank and frags have gone through same issues. I've dipped them in several dips but nothing visible. Haven't added a coral in many months. I was too full.

Might try a Revive dip to see if maybe bacterial infection...not sure if that would help.

The only event was an Alk dip that I described above quite a while back. ALK is now 7.1, CA is 500, MG is 1400. Tests done today. Ph is 8.32 and 8.31 on my two probes respectively.

Just as additional information, this is killing acro, monti, birdsnest...even pocci. Its not particular.

What lights do you use and what is the schedule

What Alk test kit do you use?


Sorry for all the questions. I have had a similar scenario where all my sps died and I'm still confused on the cause, so I'm trying to see if we have similarities.

My lights are of my own design....Cree Led along with minor T5 as a suppliment. They are all a little too high off the water (14") but they have grown my tank well for the last three years.

My ALK test is the Hanna meter. I've tried two batches of regents just in case. I also have an Elos manual kit that I checked it against periodically.

Wow, I have not updated this in forever. So as mentioned above I was experiencing some strife in the tank. Then the APEX failed while I was on Vacation and in its failure, it ignored the fallbacks as well and dumped all my dosing containers as fast as it could at once into the tank. (I had switched to 3 BRS dosers run by the APEX after my prior doser failed). This really put things over the edge and killed most of the corals in the tank that had survived the prior strife. Algae came hard after those deaths (how the fish made it through is beyond me). I've battled the algae for the last three years gaining some days and losing most. In mid 2019 I tried Vibrant and it really was what I needed to get things back on track. The tank cleaned up dramatically (although my Cheato all died) and I was able to stabilize everything.
I'm now back in game and the tank is doing mostly well. I have some cyano issues right now but I have been dealing with it. I'm back on prodibio and that has helped as well. I was lucky to get some help from local reefers and a few orders from Marine Experience to re-stock the tank with SPS. I will be using Aquaforest products to color things up and strengthen the corals as they grow.
My lights have been giving me issues for a while now and I'm currently debating moving to fixtures if I can make the pricing work. My lights were never full spectrum and so I always wondered if I could get more color from my SPS if they were.
I've attached a few pics to give an idea on how it looks.

looking good Mark.
