Nems keep wasting /going gray

[RichReef]

Do you have snails? When I had high salinity (not knowing) the first things to go were the nems and snails. Quickly followed by the shrimp.

Nems don't like nitrates, high salinity, or metals. Especially copper. They like clean water.

The depth of the nems are all about 10" or less below light. The light is a 36 inch centered on aquarium top

Am assuming 100% blue?

The website says the par at my depth should be about 150 and we have great flow

I think that is based off of all channels at 100%

Salinity in 25, 0 copper, snails and all crustaceans including shrimp and all other nems are very happy. Dosing vodka to reduce phosphorus and nitrate

No, mixed. Blue 100% morning 2 hours with an hour of blue red transition into blue white for 3 hours at 75/65, then white for an hour then reverse schedule back to blue

how old is this tank? could just be biological stability, if not icp test is always a good test to run to identify oddities

Icpc test? Tank is over a year old

Sounds like sick nems with bacterial issue that could be spreading to other nems ? It is possible although unlikely , I was expierencjng something similar btas would shrink and die I dosed cipro into DT and saved them , my GBTA were dying but rbta doing fine

This is isolated to bta only. A ciprofloxacin regimen may not be a bad plan

K.... lol.
Alk is for calcification in lps and sps corals. Nems and soft coral won't deplete alk imoe that much....

Right, I was just clarifying additional levels
