Water movement question

[dekay]

Standard answer for fighting cyano would be to shorten your photoperiod, feed once every two days, add flow and frequent water changes. But due to the somewhat incompatible fish you have in your tank (ie. the clowns), I'm not sure about the food cut back. Better leave this question to more experienced reefers.

I'd rip out the fluval though. That might be the source of your nitrate problem from the other post you had.

BTW, is the skimmer a prism or prism pro? If it's the smaller version, most ppl say it's not that efficient for anything larger than a 30 gallon.
