I feel all our energy earlier on is wasted in our quest to get an instant reef, resulting in feeling cheated when things don't pan out. I've made every mistake and then some and being stubborn and wanting to succeed keeps me going. IME The tanks biological filter and micro fauna is the most important along with stable ALK, the use of all dry rock and adding corals without this bio-diversity is a cause for many ppls failures.. After the tank is mature I see more growth and color in running higher phosphates so this idea you need low phosphates is subjective to each person tank. After this is established it just takes mastering your tank flow and lighting needs and it can take some trial and error but go lower on the lighting intensity and use your PE as a guide to flow and lighting. Observe and make adjustments only when needed.
If you love this hobby, Get your tank cleaned up, get an icp test and verify if its a unknown metal that is causing issues, do a few large water changes, lower your photoperiod (unless you know your PAR numbers), and start getting good at the things you overlooked before. Learning about the corals you want to keep, Sourcing and acclimating corals, learning about coral eating pest, ensuring you only add trace elements you can confirm your tank needs, Testing ALK religiously and keeping tabs on your feeding and how it effects your nutrient levels, adjusting or turning off your skimmer if needed. Once you can rule out all possible issues identifying an issue is very easy. Keep going!!!:)
