I currently have a 30 gallon setup that I have left sitting without much attention for about a month due to exams and college stuff and unfortunately a lot of my corals do not look great, there is brown sand and dinos everywhere, and im really upset I let it get this far without doing anything. How should I go about bringing the tank back to health. Im starting with a large >50% water change today and im going to start dosing kalk again along with dinoX. Any tips on how to get my reef back to looking pristine and clear!
