Why are my hammers so unhappy? Low nutrients, high cal, or something I am missing?

[MoshJosh]

N- 1.7
P- 0.01
Alk- 9.8 (about what I aim for)
Cal- 511
Sal- 1.025
Temp- 79.8 (I ordered some fans and will be shooting for 76ish)

The hammers look pretty MAD and I see some tissue recession. I plan on lowering my Cal and Temp while raising my nutrients (though I do like to keep them pretty low) but is there anything else I should consider/anything I am missing?

nitrates are on the lower side. hammers love magnesium, have you tested for mag?

 

[VintageReefer]

Hammers generally like low flow and medium par

 

[WalkerLovesTheOcean]

I agree with @NonstopSoda. Hammers need high mag. Lots of people I know struggled with their hammers until they raised it. Now their hammers are growing non-stop.

Yep need nutrients up and mine thrive with magnesium at 1400 or a little higher.

Nutrients are super low. Are you trying to run an ULNS? If not, I’ve found LPS do much better with phosphate at 0.1 ppm and nitrate at 10-20 ppm.
