Update, not that good. Lost half a head on my multi color acan and also 1 on my green acan, yeah yeah micromussa bla bla. Water tests from Saturday are in check and still stable, the alk and cal drop is very slow and not enough to cause an issue, we are talking .1 alk a week and 10 ppm cal. I am ordering BRS 2 part starter on Friday along with some Neo Nitro. Not sure why the sudden tissue lose on the acan/micro, growth has been good on them with several new heads growing. I do feed them a couple times a week as well. I will keep an eye on them, so far it has not gotten worse and the other heads look good. I am ordering the Neo Nitro because I cant get a detectable no3 reading at all. I dont want to feed any more heavily and Red Sea Coral Nutrition has increased my need to clean the grren film off the glass. SomI am just going to dose no3 to get a detectable 1-3 ppm and see how the tank responds. I have also stopped running the filter sock for now to "dirty" it up some. Current tests.
Alk 8.1 dkh
Cal 410 ppm
Mag 1340 ppm
No3 0.0 ppm
Po4 <.08 ppm
Salinity 1.025
