P04,N04, Kh balance check

[Afkomjorgen]

Hello!
Ive just done some testing since coming back from vacation. The tank looks good, lots of growth, but we lost a large invert without specific cause and I wanted to see where things were.
We run a higher nitrate tank typically, fyi.
I’m aware that I need to add fresh h20 and add calcium.
As far as the balance between p04, nitrate and alk, where is it at before I start fiddling with things?

I would appreciate advice from @Katherine Corals as well if they have an opinion, as they have a similar tank.

Salinity 1.029
Nitrate 40ppm
P04 .25-.50
Kh 7
Ph 8
Calcium 370
Nitrite 0

tank is mature 3.5 years old,reef
thanks

You probably want a bit more alkalinity. What invert did you lose?

Try an abalone. Those things are very tough.

I don't know if any of those parameters caused an issue.
