View Full Version : Is this REALLY All the Output from Octo/Varios 4 Pump?

Just assembled a Reef Octopus 200 Elite INT skimmer, which includes Varios 4 pump. Testing it out and this is all I see in terms of bubbles:

This sure doesn't seem like much output!

Granted, it's in fresh water in the sump (being leak-tested), fresh out of tap (i.e., no waste product), but this really seems "anemic." Yes? No?

I have no idea, but that seems really low. I do know that fresh water doesn't skim the same way as salt water does

Yea, get it in salt water. Fresh doesn't show much. I tried when I was testing my 54. Got the same thing you're getting now.

yep , they dont work in freshwater. different surface tension of the water.

Skimmers do not work even close to the same way in freshwater...
The density of the freshwater does not allow the intense bubble formation that saltwater does..

OK, salt vs fresh made a world of difference in re bubble formation and foam production. Here are photos and videos immediately after putting the skimmer into about 5 gallons taken out of nano after stirring up substrate and doing a water change. (Click on first one to get to video; still trying to figure out link from Flickr)

Question remains, though, as to whether the overall flowrate is still on the low side. Shouldn't the chamber under the dispersion plate, inside the cylindrical ring, be fairly filled with churning water? I would have thought so. Then again, my last skimmer was a BK200 (don't recall pump, sold when my system crashed during move 8 years ago), which is admittedly at a different price-point than Reef Octo.....)

Thanks for your input.
