As to my skimmer, don't ask. After seeing EmilyB's I am humbled; it must be similar to yours, Doug. About the width of a fish barrel.

Anyone have a competent skimmer they aren't using???

As to the green water solution, I'll certainly check the archives, thanks Victor.

As to diatomaceous earth (?), I have no idea but thanks for the input Bob.

I fit 3 bags of carbon across the final trap in the sump, and unhooked the Fluval - couldn't stop it making bubbles. HTH.
