Reason for water to turn greenish, the fish seem to love it.
I do not see algae bloom.
 
the green-ness is an algea bloom.

the possible reason is that the nitrates are too high in your tank.. what are your parameters?
 
You have excess algae nutrients somewhere...too much light, nitrates etc. Adjusting the tank to the correct water parameters, temp and cutting down on the amount of light the tanks has can help. If it gets quite bad a true diatom filter can cut most of it out so you can get the water levels under control.
 
OK, the lights are on most of the dayn 12hrs, will cut down and will cut down on the feeding and see what happens
thanks
 
20% water changes 2 times a week on a 65Gl tank, didn't have any problems before, had brown algae got a pleco
