Welp, here we are 2 months later and I'm about ready to throw in the towel.
Everything was going great up until about a week ago. Rocks were clean and growing a lot of calcareous algae, my nutrients were steady at 7.5N and 0.03P. Then, seemingly out of no where, DINOS.
UV has been running on the system the entire time. It knocked out the other dinos in 24hrs when it was installed. I can only assume they've been replaced with the large cell variety.
There's also a good bit of GHA, which I'm fine with, but nothing will touch it because of the dinos.
I'm open to any and all suggestions, but I haven't seen temperature increases or silicate dosing as an effective treatment in the past.
