Sorry for the delay.
The system is maturing, not as quickly as I would like, but maturing. I can attribute the slow pace to using 100% dead rock. High quality seasoned live rock, such as Tampa Bay Saltwater is the best method. Never doing 100% dead rock again. 22 months in and I am just starting to see signs of a mature system. With a mature system mistakes can be made and the system does not reactor negatively. The old salts out there know what I am talking about.
Still running AF. I run my nitrates at 2 - 5 PPM and phosphates at .02 - .05 PPM. I stopped running AF ABVE because of my moderate nutrient levels. Only running Pro BIOS and NP Pro. For those hobbyist that rinse Zeomix several days in advance of using it, ensure that you make note of the day the media was rinsed. Otherwise, a blanket of silicate based brown algae film will form on glass and sand bed. Guess how I became aware of this scenario.
Came home today to a Luxcore metal halide ballast not working. Initial troubleshooting indicates a ballast problem, not a bulb problem.
