You need some nitrates, the corals are hungry, are you dosing anything?

Also look into the amount of light, as well as some wild acros will be stressed when moved.

Have to fertilize your garden. Make sure they have PO4 0.02-0.08 and NO3 5-30.

You mean 5 -30 ppm NO3? Do I have to reduce my dosage of vodka/vinegar?

 

[Bronx19]

You just want detectable nutrients really, and make sure its more NO3 than PO4 otherwise you get into Cyano trouble.

Okay will give it a try

Agree with the others, have you changed your light settings recently? And as they said, make sure you have a tiny bit of nitrates and even less phosphates. They should be close to zero but not zero. You can stop dosing vinegar for a few days and up your feeding a bit, maybe using something messy like defrosted mysis. Plus your fish will really love you for all the tasty food haha

Only have 6 small fish in a 50 gallon tank the tank is mostly filled with corals and clams.Will stop dosing VVS for a few days and will see what happens.
