Even though your numbers went up slightly as you indicated your tank matures they were not high at all. Why even put more chemicals in to lower them? Was your tank showing negative reactions? Seems like it is easily managed with proper feeding and water change? Maybe more wet skim? Just don't see the point of always reacting with chemicals dosing.
Glad you asked. Since the nutrients and alk started increasing I have been experiencing STN of 2 SPS colonies. I'm very big on stability and was trying to bring my nutrients back in line.
Reducing feedings did not bring down the nutrients and my skimmer is used mostly for pH control. However, it produces over 1000-2000ml of very wet skim a week.
I have an automated 1% daily water change.
I'm not sure I would categorize carbon dosing a chemicals.
