thanks guys
Rae--you do hugs well--I can feel it all the way from Cinc.
Mike--did a water change last week
There is something going on in the tank that I can't get my head around ----
Three sides of the glass have greened up so you can't see through them but the whole tank looks not as bright
Its like the wave length on the halides have droped to 6500 k and you get the yellow light instead of the crystal clear white light at 10000k
I am not sure if I am into an algae bloom, the reflection of the algae on the three sides of the glass or that the halides need changing
They were changed last Nov---I usually do them every Nov along with the attinics?
The berlin is still adding oxygen to the system but not skimming--and the pH has remained stable so I know its not a gas exchange problem
