Couple months ago I removed my actinic Zoomed T5 bulbs with ATI. But left Zoomed 10k day bulbs in place. Now nothing has changed or been added to my tank in the past few months except several tiny frags. Filtration is even better now then in the past. Use UNCW water and always have. Have always used bottle water or tap with water conditioner and never had issues.Once a week water changes. All corals have always grown good. Only thing i can figure that is causing the green film on the glass is two different brands of lights mixed?Front glass is where it really grows mainly where the two 10k bulbs are. I have been discussing this with hypnoj and he thinks the lights wouldnt cause this. Just trying to get any other ideas. Thanks.
