I am documenting my fight with Dino's. Tank info, Tank is 125 Gallon, 55 Gallon sump, Reef Octopus Regal 200INT, 4 Kessil A360X's, somewhere around 115 pounds of live rock (mostly Fiji, a Pukani), about a 2" sand bed of standard sand, currently running as FOWLER. A few years back I had a bad algae problem, hair algae, all kinds of algae. My nitrates and phosphates were super high, I think NO3 was maybe as high as 30. Phosphates were WAY WAY over what the red sea kit could even test for. I then started using GFO which with GFO and using the high resolution red sea test kit I could finally get a reading. I think it was still like maybe 4 (yes 4, not .4). I then bought a large Reef octopus bio-pellet reactor. Even after I brought the bio-pellet reactor online, I continued to run GFO. Between the bio-pellet reactor and GFO, my NO3 dropped to I think about 4, and PO3 dropped to maybe .1. Tank started looking great. I thought I had fixed everything, stopped testing. Then maybe a year later everything started, started getting cyano. Problem was light but annoying. I tried correcting it with water changes. Never realizing that my NO3 had bottomed out to zero, and my PO4 to .1. I thought this was a good thing so I never considered it part of the problem. I then proceeded to use Chem-clean. Which wiped out the cyano, but within a day or two ushered in my new nemesis, Dino's. At this time (about sep 2019), I had no idea even what Dino's were. I sent away a Triton ICP test and it came back really high levels of Copper (40ppb) and a few other metals. So I thought the metals were my problem. So I dealt with the metals issue, but the DINOS persisted. I eventually came across the DINO thread on Reef2Reef. And that brings me to this week. My rock was so encrusted with dinos, my sand so covered, and the tank so covered, I knew I had to manually remove as much as I could.
