View Full Version : How's your skim??

So I hooked my hob skimmer onto my tank. The skimmer was used for a month or two by someone else. My skim isn't coming out Brown like people say. It's mostly water? Is that normal. This is the first time a skimmer has ever been on this tank and its been up and running for 4mnths.

You may have it set for the bubbles to go too high. If they spill over into the cup before they have had ample time to collect the gunk build up, you could be seeing mostly clear output. I don't have a hob, I have four different skimmers going right now. When the water level gets too high on any of them, they output too fast and it is diluted instead of the thicker green/ brown skim they do when the levels are set. If you can adjust it so the bubbles are an inch or so below the top of the neck where it overflows into the cup, you will probably get thicker darker skim collection.
