Hiding green tip anemone

[Richards Aquarium]

My green annenomes are hiding behind center rock. I got them 4 days ago.
Ph has been low 7.9 always low I try to raise it with buffer and it's a losing battle go's up then comes down.
Ammonia 0
Nitrite 0
Nitrate 20
Calcium 320-360 I need to get it up
Phosphorus 0
Alkaline 10
Salinity 1.024
Temperature 84 treated ick and bring temp down to 78.
Any help would be appreciated

This is a fish only tank I bought the annenomes for my clowns but my porcelain crabs took up residence. I also have a purplee tip annenome who's is not totally hiding. I'm not sure how to adjust the lighting either.

I have a bubble tip that split into 8 and one of them has been hiding for three months. It wanders a bit and came out at the top of the backside (and dark side) for a few weeks and then it went back into hiding. Two days ago it had split and now the two are moving around into the light zone again?

They sometimes move around and hide and if they don’t come out then I get worried that they are sick but I would just keep an eye on it (if you can see it) and hope that it settles in someplace nice.

ViparSpectra are pretty strong. And if I'm seeing that picture correctly, it looks like it's an inch or so from the water line. That's way too close. Ideally you want it up 12 to 14 inches off the water. I run Vipar lights and have them set at 50% blue, 10% white.
