LPS can be like that.. they look good for a month or two or three. Until they can't sustain themselves well and go south 'quickly'.I’m taking note on that one, thank you all for your inputs, I thought i’m doing it right because they look fin prior to last week. Thank you so much
With hammers and other similar corals look at the flesh around the top outside of the skeleton. Looks like there is still a good amount but it also looks like there is a noticeable band of white skeleton which tells me it has lost a fair amount in a short period of time which is a warning sign.
Your salinity is low. Could go to 1.026sg I use 35ppt which is a touch higher than 1.026sg This is probably why your Ca and Mg are testing low. So rather than dose those, I would bump your salinity up a little which will help the stony corals.
Any particular reason you are running 76f? On the lower end but not necessarily a big deal. Most reefers use 78-79 I think?
