Bleaching Monti?

Baby Ray · Apr 13, 2016

All my parameters are perfect and I haven't changed the amount of light it is getting. Also my other monti is looking perfect and my calcium is 450.
The bottom part of the orange monti looks bleached.

Check for monti eating nudi's. They usually start eating at the base and move upwards. If you can, remove the coral and perform a dip and see if any fall off.

Any "stingers" close by? Or maybe vermetid snails that will sting with their sweepers?

^^^^^ both my thoughts too ^^^^^^^
It can be as simple as just flow.
Constant flow from a the returns can be a factor too.
Monti's are just SPS and they hate constant flow.
Also please post your test results here,
ALK
CAL 450. Which test kit you use for that.
MAG
PH
No3
Po4

Unfortunately, that does look to be the tracks of the montipora eating nudi. I could be wrong, your going to have to try to get a look underneath the monti. Ive had monti caps grow for a little longer then a year, and started getting white trails toward the middle of the colony.I snapped the colonys off to see over 100s of them underneight

Agreed on getting full parameters. High alk, or alk swings, in a low nutrient system has proven to create problems as well, at least for me.

Baby Ray · Apr 14, 2016

Salinity 1.024
Nitrites 0
Nitrates 0
Ph 8.12
Alkalinity 10.5
Calcium 450
Magnesium 1290
Phosphates 0

I get my water tested at my LFS and these numbers were taken not to long ago

It might be the flow not changing because I haven't changed it up since I got my RBT because I am afraid it will move and kill some of my corals. I got my RBTA several months ago.

I don't have any brand name coral dipping products. Is there anything else I could dip it in? RODI water?
Thanks

I would get some coral dip for the future just in case. It is good to dip prior to adding any new coral to a system. If you are able to move the monti and dip it in fresh RODI, you can try that. If the monti is on a plug, hold it by the plug and swish it around in the fresh water and check underneath the coral.

It is on a plug and it is not glued down so I will try the RODI. definitely going to get some coral rx next time I go to my LFS

Or if you're at Home Depot, grab a bottle of this.

Please do NOT do a rodi "dip" the short amount of time the coral can be in the dip and possibly survive isn't long enough to knock any parasites off. Do yourself a favor and just don't do it, go to lowes or home depot and grab some Bayer. 10ml per 4 oz of tank water for 15 minutes.

Fresh water dips are extremely harsh on any sps corals.

Haven't done anything yet. I'll get some of that next one I can. I might take the monti out and visually inspect it.

Good to get clarification on that

Agree that the localized white patches look like they could be from pest nudibranchs. Be aware that dips (either Coral Rx or Bayer) can kill the nudis but sometimes (usually?) do not kill the eggs, so before dipping make sure to visually inspect and scrape off anything that looks like either nudibranchs or egg masses, and plan to re-dip periodically to catch newly-hatched ones. They can also get in between the coral and the frag plugs where it's really hard to spot them.
