Coral identification and dosing advice

[newreefer_59]

Hello Canreefers. Just wanting to verify some LPS coral I have as I was told it was a blastomussa when it was purchased, but someone had later said it may be an Acan Lord. Attached here is a pic.....and on the same rock this coral is attached to is a Xenia I believe. Can someone verify if this is an Acan Lord? It does appear to be very healthy.

Secondly, the Clove Polyp is about the size of a toonie. It is what this is? I have it in the 1/3 bottom of my 150 gallon tank and with med light and flow and seems to be doing well.

Most of my coral is LPS with an Aussie Acan, a nice Chalice and the aforementioned Acan Lord. I also have some softies such as a Zoanthid and some mushrooms. My SPS is a Bird's Nest and Monti - to date.

So re: dosing. Not sure if I should start routinely dosing (ex: Magnesium, Calcium, Strontium) like so many reefers do. My tests all seem to be in a good range with Cal @ 420, Ph @ 8.3, Pot @ 400 and Mag @ 1350. However, alk measured at 7.5. In your opinion, are these acceptable?
