monti loosing colour

[moosehead]

Tested my K and it's around 370 using a salifert kit. Is this low enough you think to be causing my problem ?

Hmm, that's not far off from optimal range (380 ppm).

Try moving it to another part of your tank. What bulbs are you running and how old are they?

they are around 5 months old but when i first got it the colour was bad like a dark brown grey . now is super light.
