Montipora getting white patches

With monti's, too much light will typically show little polyp extension and yes they can start bleaching. Some of my month's do best on my sand bed and have crazy polyp extension and color.
Too little light can create dull/brown colors.
It could also be unrelated to your lighting.
What monti are we talking about and where is it in the tank? What lighting?
 
Do the white places look like this? (sorry for the bad picture)

Here are my parameters, just tested,
salinity- 1.024
Ph-8
Ammonia-0
Nitrite-0
Nitrate-0 (I tested this 3 times)
Copper-0 (I have the kit so I tested)
Carbonate hardness-7 (just got this kit, I know it is a hair low)
Phosphate-0 (this is a surprise as I don't use ro-di, but I have a spring)
Alkalinity - I can't test this yet
Calcium-420 (heh heh)

I just got the phosphate kit because I expected to have phosphates since I don't use ro-di, I also tested my spring water with it, tests 0 also.
 
Most of my tests are API because that is what I have easy access to at the moment, I'll get the big *** sera box when I have the money, I just got my skimmer so I'll have to go without it a month or two
 
Kk ideas, how long does it take bleach to evaporate off my socks, I rinsed them thoroughly and let them air dry 2 days, and am running carbon for funsies, but all the tiger pods I dumped into my fuge seem to be dead, can I test for chlorine bleach?
 
Two ideas of what's going on. IME, alk swings will burn montis anywhere, unlike some other corals like acros that typically get burnt tips. Being that you haven't tested and tracked alkalinity leads me to believe that's likely the culprit.

Second, is salt creep landing on the monti. Due to way montis grow, with their big plates, lots of stuff has a tendency to land on them. Salt creep being one of them and it will burn the coral.

If you're going to keep hard corals, you'll need to monitor alkalinity. Most important parameter for hard corals.
 
Kk ill order a kit today

I'm surprised none of my LFS had a kit in stock, but I'll hit the intarwebs and order one up...and no on salt creep...yet lol

Those places were caused by a combtooth blenny biting it. Sometimes fish you wouldn't think of being a problem do.

I have a Bicolor blenny, his current favorite spots so watch the tank are all within 10" of that frag...and the spots are roughly the size of the clean spots when he takes a nip of diatoms...very suspicious lol
