Another pic that should answer your questions........
I use the Fluval foam pad in the fine filter holder and then some chaeto algae, followed by 11oz bag of Chemie Pure Elite, then some Seachem Purigen and another 11oz bag of Chemi Pure Elite.
The skimmer water exits almost the same area it comes in, at the bottom of the skimmer.
Hope this helps

Tok, very helpful pictures. Thanks. Can you tell me how often you change the Purigen and CPE? Also, do you have/need a light for the chaeto?[/URL]
