Hammer corals

[Kial]

No matter what I do, I just cannot keep hammer corals happy. They do ok for a few weeks and then slowly start to see the skeleton ok the edges.

Have tried pretty much no flow, to medium etc. I see videos of other peoples hammers in a fair bit of flow but If I put mine in anything similar. Guaranteed death.

Alk 7.5
Calc 470
Mag 1450
Nitrate 5-10
Ph 8.1
Salinity 1.025
Phos 0.03 but have algea so I'm guessing that's actually higher

Under 2x hydra 32s

Anyone got any tips?

Parameters seem fine. How old is the tank ? Have you noticed any pests such as flatworms ?

what happens in those few weeks?
Do you do water changes?
Do you dose anything?

Tanks about 7 months now. And no pests that I can see, I dip everything also

Weekly water changes and I have calc/alk/mag supplement that I manually dose
