Update:
I have a bit of unfortunate news regarding the tank. I will do my best to keep it short. I acquired 2 liters of Life Bio Fil in San Diego, months back, brought it home and put it online passive in a basket. I then removed 4 liters of matrix, it was already in a basket passive, so I simply took the basket and set it outside, where it was exposed to weather. At first this transition went well, and I was able to still achieve my same normal parameters, despite a net loss of 2 liters of bio media. I still had 2 liters of siporax that ran active in a reactor, and now 2 liters of Life Bio Fil.
During this time, My nano was empty, so after a couple of weeks of the matrix sitting outside, I though what the heck, there is nothing in the tank, so I put the matrix in the nano, there was no life, so I thought maybe the bacteria would come back. So after 2 weeks, of running in the nano, I had the great idea to put the matrix back in my display, HUGE MISTAKE! My nitrates were steady around 5ppm, increased due to the net loss of 2 liters of bio media, still a good number, and corals looked great, so I thought the matrix would then bring me down to 1-2ppm, then I could feed like crazy. Well, after a few days and into the next week or two, I noticed my Red Robin was looking really drab, like washed out. My nitrates had increased to 20ppm, other corals were really starting to darken, so I pulled the matrix.
I did some water changes, and managed to pull nitrates back down to 10ppm, but the damage was done, because the Red Robin was irritated, it stopped growth, and due to it being a larger colony, this caused my KH to increase. I was steady at 7.56 dkh for several months, but due to this one coral stopping it's growth, my alk shifted to 8.5 slowly, unsuspecting to me. This process began with the increased nitrates, but over several days and weeks, the alk was growing, given my params were super stable, I did not see the firestorm coming.
When I tested at 8.5dkh, I was now experiencing tip burn on the Red Robin, which then went to my Blue Tort, Chips Acro, and Slimer. It seems the stags do not like this alk level. I should have not stayed at 7.56dkh, given a 1 point increase is most certainly where the corals will start to get ****ed, so I have since brought that value to around 6.8-7.0 dkh, this gives me a bit more wiggle room. So, all in all not a good month, but the tank is on the mend, and the other sps in the tank look amazing, so a few ****ed corals won't ruin my day
Biological/ Equipment Update:
So I was lucky enough to get the AF 150 Reactor recently, and I found some Sera Siporax at the last Aquatics show I attended. So I am now running 5 liters of siporax in the AF 150 reactor, and 2 liters of Life Bio Fil in a TLF 550 reactor. So that is a total of 7 liters of bio media. This switch happened a week ago, and with no water changes I am now back down to 2.5ppm on nitrates and 0.02 on Phosphates. Isn't life on the reef a blast
