What do you mean wet? Also testing was done yesterday

First step to consider is to check for flukes as they can cause all of the symptoms you listed.
A freshwater dip for 4-5 minutes will confirm or eliminate flukes.

Wet would be fish, corals, inverts, macro algae, etc.

Can you see flukes? Also fresh water dip in rodi or just tap?

RODI temp matched to the tank temp. Use a dark colored container and look for white ish sesame seed sized things after the dip. If they are there they usually start dropping off at about 3 minutes.
