Coral issues

[fsenneron]

Hi there,
I started a 60 gal reef tank 6 months ago and I start having issue with some corals and my anemone (see pics). My 2 clowns are going well as my starfish and all snails and crabs.
- I feed my corals with daily redsea AB+ coral nutrition dose.
- All parameters are ok : 0 NH3, 0 NO3, ph : 8.2 Ca : 400, Phosphate 0.25 ppm
- For the flow, I have 2 MP10 (50% reef mode) and an Vectra S2 (50%)
- SKimmer always on and Biopellet always on.

For feeding, I'm using frozen reef food and turn flow off for 1 hour every day.

If anyone has an advice, I will take it ! I realy want to save them

Thanks !

Fabien.

Don’t feed too much
Zero Ammonia and nitrate- WHAT TEST KITS ARE YOU USING?

I'm using RedSea and API test kit

You need some nitrate for corals or they starve and die

So should I stop the biopellet reactor or the skimmer or both for a moment ?
Or feed more ?

zero nitrates- get them up
lower phosphates, those are quite high..

my corals i found like anywhere from .03-.01 and are happy

Agree with others, get that nitrate UP!

Also one hour with flow off is quite a long time. I'd recommend 30min max (I personally only every do 15min and still have flow on 'feed mode.'
