there are a lot of previous threads on this skimmer , just look it up in the search function. Mainly ive heard they are pretty good but have heard a few cases of them overflowing if not set up correctly. I have an reef devil from etss
Very inconsistant skimmers...they do more overflowing than anything else. When it worked...it did work. It just did not work enough for me.
There are so many better ones out there.

I think all the above post have some merit. I have had several and now am using the CCS 125. Some people love them, others don't. They can be inconsistant, but lots of that is because of other tank isssues.
