Water changes and trace elements
Here is a link that Buffy was so kind to share with me. It actually has a listing of what natural seawater has as far as trace elements and what the home aquarium has, it shows where we come up short in our aquariums. It also shows what is removed via skimming, macro algae and others.
It is a LONG read but very very informative. I hope you guys will read it and keep it in mind
