I am happy that you loved the color of the frags you received!
I can understand what you mean by zeovit look. I like it one notch darker than that, haha. I think it shows off the coral fluorescence a little better. Coral health wise there is no doubt corals are healthier with some nutrients in the water. You will get better polyp extension and faster growth. When I see the user refer to nutrients as poison it drives me insane.
Having a new piece of equipment like the sulfur reactor is always scary, especially since it needs dialed in at first. After doing a lot of reading about it, it seems pretty straight forward and hard to screw up so I’m going to give it a try. I loved using chaeto but I made my sump wrong and it kept getting sucked into my skimmer pump and clogging it so I removed the chaeto. If I can figure out how to keep it from happening I will give that a try again.
