First pic is of my HOG2 showing the GHA as it was under 18 hours of lighting.
This pic is as of now showing a shorter darker algae growth with some lighter above. I increased the lighting period from 18 hours to 20 hours.
Both had slow algae growth. I have problems with a short growing Caulerpa species in my tank and so far the scrubber has not made any difference to it. Should I go back to 18 hours lighting?
