Low Nutrients

[arranms96]

Hi Guys,

This is a follow up to my previous post regarding Monitpora health, this post can be found here - https://www.reef2reef.com/threads/montipora-issue.830317/

In the last few days most of my SPS have started to lose colour and some look like they are suffering from either bleaching or STN

My Levels are -
Alk - 8.5
Calcium - 440 (was was around 500 two weeks ago slowly trying to get it back to 420)
Mag - 1400

Salinity - 35 Tested with a newly calibrated Refractometer (Apex Salinity Probe reading 36.4)

I have just received brand new PO3 and PO4 Salifert Test Kits and both are reading 0! I think this could be my issue, I'm guessing my corals are starving?

My Flow is -

1x Jebao CP90
2 x TMC ReefTide 4000s
1 x Jebao SLW10

I feed what I would say is quite heavy, two cubes of frozen brine shrimp and a pinch of pellets per day.

My Fish Load is -
6 Blue Green Chromis
2 Cleaner Wrasse
1 Half Black Angel
1 Banggai cardinal
1 Springer Damsel (Did have 3 but he killed the others!)
1 Cleaner Shrimp
1 Peppermint Shrimp
1 6 Line Wrasse (Only Added today)

Any suggestions?

Feed a lot more and maybe dose coral foods more if you don't already.
