I would add that it's important to understand as a public forum not to take everyone's word as gospel. There are hundreds of reefers on here with decades of experience and typically advice will be correct for your situation. However, everyone's tank is unique and you know your parameters, stocking, and maintenance routine better than any of us.
In my opinion the bigger takeaway is that there is no one panacea for any reef issue and sometimes tackling the issue requires multiple approaches, or changes in your husbandry discipline. Forums are great but sometimes you can get piled with slightly different answers that can leave you astray. I would suggest picking a range of parameters you feel comfortable with and confident you can keep stable that are appropriate for your setup and do your best to stay in those ranges, rather than picking an arbitrary point to start acting aggressively. Nutrients in particular require caution as your livestock can become acclimated to heavier nutrient load, which can cause issues if they are lowered too quickly.
I say all this as a 2yr reefer (more time in freshwater) so incorporate my suggestions but don't take it as gospel; this is a forum and not an absolute authority on correct approaches (barring some chemical/mathematical stuff that is unequivocally correct by its nature).
However, if multiple people are suggesting the same thing, there is likely validity to their suggestions.
Fwiw my brother watched my tank on vacation. Came back to dinos/diatoms/hair algae explosion and spiked salinity. 1 yr later and my tank is thriving. You can get your tank back on the rails with some patience and discipline. It took some time before I was happy with it but this hobby is not for you if you don't have some level of persistence and patience.
