Especially aminos. I've seen sooo many issues caused by this.Yea dosing is because you need minerals and your water changes cannot keep up within the week to two weeks.
So as a new hobbiest and so you don’t kill your motivation with ugly stages and new theories. Just keep it simple, feed your fish and do your water changes and test once to twice a week. This will help you be more in tune with your tank since you’ll be performing water changes.
So stop dosing everything and keep it simple until you actually need to dose. Anyone who tells you that you need to dose in the beginning is 100% wrong
We have a lot of sps dominant systems and only things we do are 2 part and weekly water changes.
