More.... while my tank was cycling, the first three weeks, I did not run a
skimmer at all. I also did not run any lights. This accomplished two things, it allowed the biological filtration to take hold well in the
DSB, and it kept down the growth of algae,
cyano and other bad stuff. Just a suggestion. It worked for me. Then after the cycle was complete (towards the end I turned on and adjusted my
skimmer too) , I gradually turned on lights, two hours at a stretch, until I was at 8 hours od sunshine. This seemed to help as well.
God luck my friend!
