Green water or Bacterial Bloom

[29gallonsteve]

First I thought I had a bacterial bloom from overfeeding, now I think it is an algae bloom. I think the lighting in the tank makes it look grey.

When I look at the tank with lights on, it is white/grey, but when I just changed the water, found it to be green.

Am I correct to assume that this is actually an algae bloom that I have been waiting out (mistakenly believing it was bacterial...)?

Thanks,
Steve

If you draw a glass of water and hold it in front of a sheet of white paper, you'll easily be able to tell if it's algae or not.

HTH,

Jim,

It's definitely green (white wash tub)...is there something else (by looking thru glass) that I should see?

Thanks,

Green means algae. Too long a photoperiod, too rich in nutrients. You know the drill.

Yep...thanks, Jim.
