Nope.No sump,wet dry or refugium. What chemicals? I do use Aragamilk,PH buffer and Calcium once in awhile.

My Colt use to lean over and touch my Green Finger.The Finger would curl up on that side.Since I moved the Colt over the Finger opens more. Some hard corals/LPS have sweeper tentacles that sting others they sense nearby.My Bubble used to try to sting my Feather Duster.I moved the Bubble over too.(see pics 8&10) That trick is too find out which have the longer stingers and buy them if you have the room for them to grow.Some have shorter stingers while others have none. Again,Read about the coral before you buy it.
I do have a sudden case of diatoms for some unknown reason.
Thanks for all the compliments.
