I run my 37g, 67g and 120g BB tanks without skimmers or sumps. Don't use Chemi-pur or anythink like that to remove whatever those things are designed to remove. Do not run carbon unless there is a problem, which is maybe once every two years. Do weekly maintenance as described on my webpage (link below). Lots of pics, lots and lots of blah, blah, blah ....

The only problem not mentioned on the page is that we have is a scum build up in each tank, probably due to the rinsed PE mysis we feed soaked in Kent Zoe and Garlic Xtreme. Easily taken care of by skimming the water's surface weekly with the powerheads off.
