problem
 

the readings are all within the parameters.

i used KORDON's RID ICK. to treat the ick.

No matter what the bottle says you should never treat fish in the presence of invertebrates. So I would advise do a large water change and add carbon to your filters to remove the Kordons, hopefully your corals will recover.

after reading about the KORDON's RID ICK i think that is the problem and your frogspawn may not survive.fish should be mediacted in a quarantine tank. this was taken from there website.

"Rid·Ich+ is not recommended for use in aquariums containing invertebrates and may cause severe stress or death to some of these animals. If Rid·Ich+ must be used in aquariums containing invertebrates, tests should be performed to determine a particular animal's tolerance to this medication."
