Hello. My reef is about 3.5 years old and it's been about 1.5 years since i upgraded to a 125 gallon setup. Since then, i have not been able to control the aquarium at all and the understanding i once thought i had about nutrients and chemistry is seemingly meaningless now. My rock is 100% carpeted in gha and a small layer of ongoing dynoflagellate infestation. I can not raise my nutrients because the gha explodes, and i can not do a water change because the dinos explode. I don't know where to start but i'm really really sick of watching this thing get worse and worse. It's been a long time since i enjoyed watching the reef. Thanks in advance, sorry for not including many details but i'm so beaten by this stupid thing i just don't know where to start.
