    140 gallon reef flow design

    It stemmed from an advanced aquarist article: http://www.advancedaquarist.com/2007/1/aafeature It basically talks about using multiple point sources of water flow in conjunction, rather than in opposition to create laminar unidirectional circular flow. After a sustained period of flow in one...

    140 gallon reef flow design

    I'm in the process of putting together a 140 gallon tank (4' x 2' x 28"). I flirted with a closed loop manifold or ocean's motions permutation, but after learning about the gyre flow, I've decided that that is what I want to replicate. However, I don't want to have a permanent uni-directional...

    Octupus Xtreme skimmer

    Has anyone gotten a handle on the true size ratings for these SWC extreme skimmers? Is the 160, or 200 ratings accurate, or would you size up accordingly? I'm looking at setting up a moderately stocked 140 gallon reef with some sps corals, and I'm wondering which size (160 or the 200) I should...

    Calfo Manifold Flow Rate Question

    David, What size pipe do you run on your manifold, and what is the diameter of your outlets?

    Calfo Manifold Flow Rate Question

    class clown : http://www.advancedaquarist.com/issues/sept2003/short.htm Murfman, yeah I just got what you are saying - no vertical head loss because it is a closed loop. But I would expect that I would have frictional flow loss through the manifold, right?

    Calfo Manifold Flow Rate Question

    My pump output will not be the output of the manifold, as I will have a height difference to overcome as well. As for the no frictional losses through the manifold, that seems weird, but I'll have to think about that more later. I will have a 2" bulkhead feeding each pump, so I shouldn't have...

    Calfo Manifold Flow Rate Question

    After extensively researching the CLM concept, I've begun my design work. The problem I am encountering is that while I can quantify the expected flow rates, I cannot qualify them. That is, I cannot determine whether my x gph per nozzle is going to be sufficient for the livestock I expect to...
