Why does my encrusting monti look like this?

[Joshb757]

It’s looks white and hazy. I did a water change last weekend but the only thing that changed was my alk went up .1 The first picture is when I first got it,
The second is two week later. It’s located at the top of my tank, underneath a Fluval Marine 3.0 light 6” deep.

Water parameters:
Ph7.8
Alk 9.3
Phos 0.04
Nitrate 12ppm
Calcium 435
Mag ?
Salinity 0.026

I know the Fluval light is not the strongest in the world, but the par is still decent depending on how high you place it. What was your acclimation process?

What do you have your settings set to with the lights? I have the 3.0 and 2.0 on my 130l tank.

You need a magnesium test kit I assume? Typo on the salinity I hope

I had it on a frag rack on the side for a week then I placed it on the rock.

In my experience, when the polyps are in like that it’s a water quality issue. Check your alkalinity, and check your nutrients.

Yes and yes lol

All is the same as original post excep now phosphate is .06. I have the regular Hanna phosphate checker and idk if I can trust this thing. If I check it again it might say 0.00. I know I need the ulr phosphorous.

These lights get most of there par from the whites. Not saying its right for you but this is mine
