NEED HELP Pale Colours

[dangerrrr]

I've been having a problem with my Montis and now my acros. My colours seem to really pale. They dont go brown, they're just really pale. Growth of acros seems to be good with some showing signs of up to 1" growth of encrusting and at the tips in the last 6-8 weeks. Montis haven't grown at all though. I'm a little stumpped.

My levels are;

Phos : 0.03 Hanna
Nitrate : 0.00 Salifert
Calc : 430mg
Alk : 11.6
Mag : 1270
Salinaity : 1.025
Ph : 8.00 - 8.20
Temp : 26.5 - 28.5

I've had a good look for any nasties such as AEFW and I can t see any signs of them.

My params are always stable. I'm using a KR-92 LED light, could this be the issue despite the strong growth in most acros...?

Thanks guys!

I had the exact same problem and I was doing 10% water changes every 6-8 weeks. Then I started going 10% water changes weekly and the colors came back real quick.

How much % and how often are your water changes?
