What kind and how old are your bulbs?

Ammonia? How old is this tank?

[bigB]

The tank is 5+ years old. Bulbs are T5s, they are 6 months old. The ammonia lokks like 2-3 kinda hard the tell with the color change salfert has. I have also had the test kit for awhile so it could be getting old.

I think its the new bulbs. BTW, all my Favia have experienced at least some slight color changes..
