Let the record state, I stopped doing auto water changes on July 12th 2024 and started reef moonshiners soon thereafter.
A couple of things led to my decision. First, I had suspected that the water changes were not replenishing trace elements faster enough and Oceamo ICP testing confirmed it. A whole slew of trace elements were low or depleted and I believe that was leading to certain types of corals struggling. Second, the cost of salt made me reassess how I was doing things. I was going through a box and a half of reef crystals each month.
So, I have changed things up and keeping a close eye on things. Everything is going well at this point with the main challenge being rising phosphates, which I am managing. Nitrates have not been an issue.
