Sure it’s not time to clean your glass?

Yes, very yellow.  

 

Need more info. 

 

Filtration type

refugium and it’s contense and lighting type and schedule?

how did you run the carbon.  Example, in a reactor, in a bag sitting in the bottom.

Feeding schedule and type of food

live stock in the tank. 

Water change schedule

and some basic tests including Nitrates and phosphates.  

Water change schedule?

Anything new in the tank?

flow rate through the filters 

 

 

all all these things can contribute.

New tank? U need to up ur housecleaning regimen. Do you vacuum the sand? Need parameters, esp nitrate/phosphate. How often do u change the carbon? Scrape the glass during water change. What’s ur CUC? Is that scum or foam on the water surface, or just air bubbles. If scum or foam that could indicate high protein levels (usually nitrates or phosphates). Also, what type of rock; dry vs new cycled?
